Minicurso 1 ( MC1)<br />

Mo<strong>de</strong>los <strong>de</strong> Regressão Log-simétricos em R<br />

Luis Hernando Vanegas ( IME/ USP)<br />

Gilberto Alvarenga Paula ( IME/ USP)<br />

Resumo: In the context of regression mo<strong>de</strong>ls, the data for which the response<br />

variable is continuous, strictly positive, and asymmetric with possible outlying<br />

observations are commonly employed in various fields of practice. Being so, this<br />

minicourse provi<strong>de</strong>s a unified theoretical framework of semi-parametric regression<br />

analysis based on log-normal, log-Stu<strong>de</strong>nt-$t$, Birnbaum-Saun<strong>de</strong>rs, Birnbaum-<br />

Saun<strong>de</strong>rs-$t$, harmonic law and other right-skewed, heavy/light-tailed and strictly<br />

positive distributions, in which both, the median and the skewness of the response<br />

variable distribution are explicitly mo<strong>de</strong>led. In this setup, here termed logsymmetric<br />

regression mo<strong>de</strong>ls, both the median and the skewness are <strong>de</strong>scribed using<br />

semi-parametric functions of explanatory variables, in which their nonparametric<br />

components are approximated by natural cubic splines or P-splines. An iterative<br />

process of parameter estimation based on Fisher scoring, expectation-maximization<br />

and backfitting algorithms is <strong>de</strong>scribed.<br />

The behavior of the (penalized) maximum likelihood estimates is illustrated by<br />

using simulation experiments. A computational implementation of the proposed<br />

methodology in the {\tt R} statistical computing environment is also presented. The<br />

attractive features of this package inclu<strong>de</strong> the possibility of performing residual<br />

analysis by applying <strong>de</strong>viance-type residuals for median and skewness submo<strong>de</strong>ls,<br />

as well as sensitivity studies through local influence un<strong>de</strong>r usual perturbation<br />

schemes. Five real data sets are analized to illustrate the flexibility of the addressed<br />

statistical and computational tools.<br />

Misturas Finitas <strong>de</strong> Distribuições<br />

Camila Borelli Zeller ( UFJF)<br />

Celso Rômulo Barbosa Cabral ( UFAM)<br />

Víctor Hugo Lachos (UNICAMP)<br />

Resumo: Misturas finitas <strong>de</strong> distribuicões são utilizadas em situações on<strong>de</strong> existe<br />

heterogeneida<strong>de</strong> não observável na população. Por exemplo, suponhamos que<br />

imagens <strong>de</strong> células cancerígenas sejam objeto <strong>de</strong> estudo. Neste caso a variável tipo<br />

do tumor, classificada em malígno ou benigno, não é observável diretamente. Para<br />

classificar a célula em uma das duas categorias, usualmente observamse variáveis<br />

como raio, a textura e o perímetro do núcleo celular, <strong>de</strong>ntre outras (Street et al.,<br />

1993). Misturas finitas também constituem uma família extremamente flexível <strong>de</strong><br />

distribuições, útil para mo<strong>de</strong>lar dados que apresentam comportamento não usual,<br />

apresentando ao mesmo tempo assimetria, caudas pesadas e observações<br />

aberrantes. Os mo<strong>de</strong>los <strong>de</strong> misturas finitas tem sido objeto <strong>de</strong> investigação intensa<br />

nos últimos anos. Existem aplicações em diversas áreas, como biologia, engenharia,<br />

marketing e medicina, somente para citar algumas. Alem disso, uma vasta<br />

bibliografia está disponível, como os textos <strong>de</strong> Bohning (2000), McLachlan & Peel<br />

(2000), Fruhwirth-Schnatter (2006), Schlattmann (2010) e Mengersen et al. (2011),<br />

alem das edições especiais do periódico Computational Statistics and DataAnalysis<br />

(Bohning et al., 2007, 2014).<br />

Neste minicurso preten<strong>de</strong>mos apresentar os principais aspectos inferenciais em<br />

misturas finitas <strong>de</strong> distribuições, tanto no contexto Bayesiano quanto no contexto<br />

frequentista, alem <strong>de</strong> discutir alguns temas recentes <strong>de</strong> pesquisa na área, com<br />

<strong>de</strong>staque para aqueles que vem sendo <strong>de</strong>senvolvidos pelos autores <strong>de</strong>sta proposta.<br />

The Bayesian ability of the restricted Conway-Maxwell-Binomial<br />

mo<strong>de</strong>l to control dispersion in discrete data<br />

Josemar Rodrigues<br />

ICMC – USP<br />

Resumo: This paper <strong>de</strong>als with the Bayesian machinery for the estimation of the<br />

parameters of the correlated Binomial distribution which was generated from a nite<br />

correlated Binomial processes to solve dispersion problems. This mo<strong>de</strong>l is a<br />

restricted version of the Conway-Maxwell-Binomial (CMB) distribution<br />

introduced by Shmueli et al. (2005) which is the correlated Binomial distribution<br />

(CB) discussed in Kupper & Haseman (1978) and Bahadur (1961) if and only if<br />

some restrictions are imposed on the parameters. These restrictions give to CMB<br />

distribution the Bayesian ability to control the phenomenon of dispersion in count<br />

data toward the binomial scenery by means of the number of the correlated Bernoulli<br />

variables. An illustrative example with real data shows the usefulness of the<br />

proposed restricted mo<strong>de</strong>l.<br />

Some contributions on nonstandard regression mo<strong>de</strong>ls<br />

Dipankar Bandyopadhyay<br />

University of Minnesota, Minneapolis, USA<br />

Resumo: Periodontal studies often leads to data collected which are clustered in<br />

nature (viz. clinical attachment level (CAL) measured at tooth-sites and clustered<br />

within subjects) that are routinely analyzed un<strong>de</strong>r a linear mixed mo<strong>de</strong>l framework<br />

with un<strong>de</strong>rlying normality assumptions of the random effects and random errors.<br />

However, a careful look reveals that these data might exhibit skewness and tail<br />

behavior, and hence the usual normality assumptions might be questionable.<br />

Besi<strong>de</strong>s, periodontal progression might also be spatially associated, i.e. a diseased<br />

tooth site influences the <strong>de</strong>cay status of a set of neighbouring sites. Also, the<br />

presence/absence of a tooth is informative as the number and location of missing<br />

teeth informs about the periodontal health in that region. In this paper, we <strong>de</strong>velop a<br />

(shared) random effects mo<strong>de</strong>l for site-level CAL and binary presence/absence<br />

status of a tooth using a Bayesian paradigm. The random effects are mo<strong>de</strong>led using a<br />

spatial skew-normal/in<strong>de</strong>pen<strong>de</strong>nt (S-SNI) distribution, whose covariance structure<br />

follows a conditionally autoregressive (CAR) process. Our S-SNI <strong>de</strong>nsity provi<strong>de</strong>s<br />

an attractive parametric tool to mo<strong>de</strong>l spatially referenced asymmetric thick-tailed<br />

structures.<br />

Both simulation studies and analysis of a real data on the periodontal health status of<br />

Gullah speaking African-American diabetics reveal that our proposition provi<strong>de</strong>s a<br />

significantly improved fit over mo<strong>de</strong>ls that do not consi<strong>de</strong>r these features of<br />

periodontal data in a unified way."<br />

Some contributions on nonstandard regression mo<strong>de</strong>ls<br />

Somnath Datta<br />

University of Louisville, USA<br />

Resumo: We discuss how to extend parametric and nonparametric inference<br />

procedures when the classical assumption of in<strong>de</strong>pen<strong>de</strong>nce is violated due to<br />

clustering. Clustered data arise in a number of practical applications where<br />

observations belonging to different clusters are in<strong>de</strong>pen<strong>de</strong>nt but observations within<br />

the same cluster are <strong>de</strong>pen<strong>de</strong>nt.<br />

While making adjustments for possible cluster <strong>de</strong>pen<strong>de</strong>nce, one should also be<br />

aware of the informative cluster size phenomenon which occurs when the size of the<br />

cluster is a random variable that is correlated to the outcome distribution within a<br />

cluster, often through a cluster specific latent factor. We <strong>de</strong>monstrate the correct<br />

inference procedures un<strong>de</strong>r various scenarios.<br />

Box-Cox symmetric mo<strong>de</strong>ls and applications to nutritional data<br />

Silvia L. P. Ferrari<br />

Departmento <strong>de</strong> Estatística – Universida<strong>de</strong> <strong>de</strong> São Paulo, Brasil<br />

Resumo: We introduce and study the Box-Cox symmetric class of distributions,<br />

which is useful for mo<strong>de</strong>ling positively skewed, possibly heavy-tailed, data. The<br />

new class of distributions inclu<strong>de</strong>s the Box-Cox t, Box-Cox Cole-Green, Box-Cox<br />

power exponential distributions, and the class of the log-symmetric distributions as<br />

special cases. It provi<strong>de</strong>s easy parameter interpretation, which makes it convenient<br />

for regression mo<strong>de</strong>ling purposes. Additionally, it provi<strong>de</strong>s enough flexibility to<br />

handle outliers. The usefulness of the Box-Cox symmetric mo<strong>de</strong>ls is illustrated in a<br />

series of applications to nutritional data.<br />

Bayesian Mo<strong>de</strong>ling of Sparse High Dimensional<br />

Data using Divergence Measures<br />

Dipak Dey<br />

University of Connecticut,<br />

Storrs, USA<br />

Resumo: We introduce a novel divergence based approach, called Bregman<br />

divergence, to mo<strong>de</strong>l sparse high dimensional problems. We also introduce a new<br />

prior which induces a new version of the (approximate) adaptive lasso in a Bayesian<br />

framework. Unlike the original adaptive lasso in which the weights should be prespecified<br />

prior to the estimation, in our approach the coefficient estimates are<br />

directly used as the weights. In addition, due to the generality of the Bregman<br />

divergence, the proposed mo<strong>de</strong>l is easily exten<strong>de</strong>d to generalized linear mo<strong>de</strong>ls as<br />

well as the group lasso.<br />

Multivariate t nonlinear mixed mo<strong>de</strong>ls for<br />

multivariate longitudinal data with missing values<br />

Tsung-I Lin<br />

National Chung Hsing University,<br />

Taichung, Taiwan<br />

Resumo: The multivariate nonlinear mixed mo<strong>de</strong>l (MNLMM) has been exploited<br />

as an effective tool for mo<strong>de</strong>lling multi-outcome longitudinal data following<br />

nonlinear growth patterns. In the framework of MNLMM, the random effects and<br />

within-subject errors are routinely assumed to be normally distributed for<br />

mathematical tractability and computational simplicity. However, a serious<br />

<strong>de</strong>parture from normality may cause lack of robustness and subsequently make<br />

invalid inference. In this talk, I introduce a robust extension of the MNLMM by<br />

consi<strong>de</strong>ring a joint multivariate t distribution for the random effects and withinsubject<br />

errors, called the multivariate t nonlinear mixed mo<strong>de</strong>l (MtNLMM).<br />

Moreover, a damped exponential correlation structure is employed to capture the<br />

extra serial correlation among irregularly observed multiple repeated measures. An<br />

ECM procedure coupled with the first-or<strong>de</strong>r Taylor approximation is <strong>de</strong>veloped for<br />

estimating mo<strong>de</strong>l parameters.<br />

The techniques for estimation of random effects, imputation of missing responses<br />

and i<strong>de</strong>ntification of potential outliers are also investigated. The methodology is<br />

applied to a real data example on 161 pregnant women coming from a study in a<br />

private fertilization obstetrics clinic in Santiago, Chile.<br />

On local power properties of the LR, Wald, score and gradient tests<br />

in nonlinear mixed-effects mo<strong>de</strong>ls<br />

Artur José Lemonte<br />

Universida<strong>de</strong> Fe<strong>de</strong>ral <strong>de</strong> Pernambuco, Brasil<br />

Resumo: The local powers of some tests un<strong>de</strong>r the presence of a parameter vector,<br />

omega say, that is orthogonal to the remaining parameters are studied in this paper.<br />

We show that some of the coefficients that <strong>de</strong>fine the local powers of the tests remain<br />

unchanged regardless of whether omega is known or needs to be estimated, whereas<br />

the others can be written as the sum of two terms, the first of which being the<br />

corresponding term obtained as if omega were known, and the second, an additional<br />

term yiel<strong>de</strong>d by the fact that omega is unknown. We apply our general result in the<br />

class of nonlinear mixed-effects mo<strong>de</strong>ls and compare the local powers of the tests in<br />

this class of mo<strong>de</strong>ls.<br />

Nonparametric Bayesian regression<br />

Peter Mueller<br />

University of Texas,<br />

Austin, USA<br />

Resumo: We first review some common approaches to nonparametric Bayesian<br />

regression. We briefly review regression with nonparametric residual distribution,<br />

nonparametric mean function and fully nonparametric regression (<strong>de</strong>nsity<br />

regression). We then focus on the latter and discuss in more <strong>de</strong>tail a novel mo<strong>de</strong>l for<br />

regression with a variable dimension parameter vector. The motivating application<br />

is subgroup analysis for a clinical trial of targeted therapy. The covariates are<br />

indicators of genetic aberrations, with each mutation only being recor<strong>de</strong>d for a small<br />

subset of patients.<br />

We construct the <strong>de</strong>sired regression mo<strong>de</strong>l as a covariate-<strong>de</strong>pen<strong>de</strong>nt random<br />

partition mo<strong>de</strong>l, using for each patient only the available mutations.<br />

Analysis of aca<strong>de</strong>mic performance of stu<strong>de</strong>nts via<br />

quasi U-statistics and generalized linear mixed mo<strong>de</strong>ls<br />

Hil<strong>de</strong>te Prisco Pinheiro<br />

Department of Statistics, University of Campinas, Brazil<br />

Resumo: We present methods to assess un<strong>de</strong>rgraduate stu<strong>de</strong>nts’ performance.<br />

Emphasis is mainly given to potential dissimilar behaviors due to high school<br />

background (Private or Public), but socioeconomic status and <strong>de</strong>mographic<br />

characteristics may be used as well. Two analysis are presented: one based on a<br />

nonparametric method using measures of diversity and a <strong>de</strong>composition of quasi U-<br />

statistics to <strong>de</strong>fine average distances between and within groups; and another based<br />

on generalized linear mixed mo<strong>de</strong>ls (GLMM). An advantage of the nonparametric<br />

method over the classical analysis of variance is its robustness to distributional<br />

<strong>de</strong>viation from the normality. Moreover, compared with other nonparametric<br />

methods, it also inclu<strong>de</strong>s tests for interaction effects which are not rank transform<br />

procedures. Two data sets are analyzed, being both of them from the State<br />

University of Campinas (Unicamp). The first one is formed by stu<strong>de</strong>nts who<br />

enrolled at Unicamp between 1997 and 2000 and their aca<strong>de</strong>mic performance has<br />

been recor<strong>de</strong>d until graduation or drop-out. The second data set is formed by<br />

stu<strong>de</strong>nts admitted to Unicamp from 2000 through 2005 and their aca<strong>de</strong>mic<br />

performance and socioeconomic variables forms the study database. For each<br />

stu<strong>de</strong>nt we have the Entrance Exam Score (EES), the final Gra<strong>de</strong> Point Average<br />

(GPA) score as well as the number of courses he/she failed during his/her Bachelor’s<br />

<strong>de</strong>gree. The courses are separated in two categories: Required and Elective.<br />

Therefore, for the GPA score and the number of courses failed, each stu<strong>de</strong>nt may<br />

have at most two measurements. We mo<strong>de</strong>l the GPA score and the inci<strong>de</strong>nce of<br />

courses failed for Required and Elective courses according to the EES,<br />

socioeconomic and <strong>de</strong>mographic characteristics.<br />

Exten<strong>de</strong>d Families of Continuos Distributions<br />

Gauss Cor<strong>de</strong>iro<br />

DE – UFPE<br />

Resumo: The construction of some wi<strong>de</strong>r families of continuous distributions<br />

obtained recently has attracted applied statisticians because the analytical facilities<br />

available for easy computation of special functions in programming softwares. In<br />

this talk, we outline some recent generating families of continuous distributions and<br />

discuss some of their properties. We review the beta, Kumaraswamy, gamma and T-<br />

X families of distributions. Some special cases, which are natural members of these<br />

families, are presented. Several known continuous distributions are found to be<br />

special cases of the current families. These properties are not difficult to be<br />

implemented in programming softwares such as R, MATHEMATICAand MAPLE.<br />

Some examples illustrate the potentiality of the new mo<strong>de</strong>ls.<br />

Nonparametric Regression and Partial Least Squares<br />

Dimension Reduction in Multistate Mo<strong>de</strong>ls<br />

Susmita Datta<br />

Resumo: In mo<strong>de</strong>rn medicine one may be interested in predicting the stage<br />

occupation probabilities of different stages of the disease of a patient from high<br />

dimensional genomic and proteomic profiles. We introduce a method of<br />

constructing non-parametric regression estimates of state occupation probabilities<br />

in a multistate mo<strong>de</strong>l.<br />

In or<strong>de</strong>r to tackle a potentially large number of predictors in mo<strong>de</strong>rn genomic and<br />

proteomic data sets we use partial least squares to compute estimated latent factors<br />

from the transition times along with the covariates which are then used in an additive<br />

mo<strong>de</strong>l in or<strong>de</strong>r to avoid the curse of dimensionality. We illustrate the methodology<br />

using simulated and real data sets.<br />

Testing Association without Calling Genotypes Allows for Systematic<br />

Differences in Read Depth and Sequencing Error Rate<br />

Between Data from Case and Control Participants<br />

Glen Satten<br />

Centers for Disease Control and Prevention,<br />

Atlanta, USA<br />

Resumo: The quality of genotype calling for next-generation sequence data<br />

<strong>de</strong>pends on read <strong>de</strong>pth. Loci with high coverage can typically be reliably called,<br />

while those with low coverage may be difficult to call. In a case-control study, if data<br />

from case participants is sequenced to a greater <strong>de</strong>pth than data from controls, the<br />

difference in genotype quality can introduce a systematic bias. This can easily occur<br />

when historical controls (e.g., data from the 1000 Genomes Project) are used. This<br />

imbalance may also occur by <strong>de</strong>sign, to reduce genotyping costs among controls.<br />

For trios, bias can arise even when the coverage is the same in parents and offspring<br />

since errors in parental genotype calls are consi<strong>de</strong>red non-transmissions while<br />

errors in offspring genotype calls are <strong>de</strong>tected as non-Men<strong>de</strong>lian transmissions.<br />

Methods: We <strong>de</strong>velop likelihood-based methods for analyzing data from casecontrol<br />

and trio studies that directly uses data on reads without first making<br />

intermediate genotype calls. When the location of polymorphic loci is known, we<br />

show these likelihood approaches have appropriate size and good power compared<br />

with methods that use called genotypes. When the locations of polymorphic loci are<br />

not known in advance, we <strong>de</strong>velop screening methods to screen out loci that are<br />

estimated to be monomorphic, based on read data alone. We use a bootstrap<br />

approach to estimate which of the loci that screen in are truly polymorphic. Using<br />

these estimates, we then construct bootstrap tests for association that properly<br />

account for screening and preserve size. We further show that restricting to loci with<br />

estimated allele frequency ≥ 1/2N, so that the expected number of alleles seen is<br />

greater than one, increases the power of our approach by excluding loci that have<br />

negligible effect.<br />

Results: We illustrate our approach using data from the UK10K project. We use data<br />

from 784 cases from the Severe Childhood Onset Obesity Project, and are exome<br />

sequenced at 60x. Data for 1702 controls are from the Avon Longitudinal Study of<br />

Parents and Children and the TwinsUK study (only one twin used), and are whole<br />

genome sequenced at 6x coverage.<br />

Sommath Datta<br />

University of Louisville,<br />

Louisville, USA<br />

Resumo: In this talk, we will cover various elements of prediction using Big Data<br />

leading to a high dimensional covariate. Typically, such data have inherent noise<br />

along with useful signals that are predictive of certain discrete or continuous<br />

outcome. Therefore <strong>de</strong>noising and feature selections are useful steps in constructing<br />

useful covariates that can be used in a statistical regression mo<strong>de</strong>l.<br />

Next, we review various mo<strong>de</strong>rn regression techniques, including latent factor and<br />

penalized methods, that are suited to handle large covariate vectors. In the final part<br />

of the talk, we cover the Super Regression method that is an ensemble method and is<br />

suitable for the Big Data paradigm.<br />

Imputation of confi<strong>de</strong>ntial data sets with spatial<br />

locations using disease mapping mo<strong>de</strong>ls<br />

Thais Paiva<br />

Department of Statistical Science at Duke University, USA.<br />

Resumo: Data that inclu<strong>de</strong> fine geographic information, such as census tract or<br />

street block i<strong>de</strong>ntifiers, can be difficult to release as public use files. Fine geography<br />

provi<strong>de</strong>s information that ill-intentioned data users can use to i<strong>de</strong>ntify individuals.<br />

We propose to release data with simulated geographies, so as to enable spatial<br />

analyses while reducing disclosure risks. We fit disease mapping mo<strong>de</strong>ls that predict<br />

areal-level counts from attributes in the file and sample new locations based on the<br />

estimated mo<strong>de</strong>ls.<br />

We illustrate this approach using data on causes of <strong>de</strong>ath in North Carolina,<br />

including evaluations of the disclosure risks and analytic validity that can result<br />

from releasing synthetic geographies.<br />

An analysis of functional MRI with a three components<br />

hemodynamic response function<br />

Marco Ferreira<br />

Department of Statistics at Virginia Tech, USA<br />

Resumo: We <strong>de</strong>velop a novel methodology for functional magnetic resonance<br />

imaging (fMRI) analysis based on a three components hemodynamic response<br />

function. Specifically, we propose a novel hemodynamic response function that is a<br />

mixture of three gamma <strong>de</strong>nsities. In addition, we use a Johnson-Rossell nonlocal<br />

prior to mo<strong>de</strong>l the regression parameters associated to neuronal activation.<br />

Further, to estimate the mo<strong>de</strong>l parameters we <strong>de</strong>velop a Markov chain Monte Carlo<br />

algorithm. Our hemodynamic response function is flexible enough to accommodate<br />

distinct physiological responses in different parts of the brain. We illustrate our<br />

methodology with the analysis of a single-subject fMRI visual task experiment.<br />

Latent Structure mo<strong>de</strong>ling in Spatio-temporal small area Health data<br />

Andrew Lawson<br />

Dept of Public Health Sciences, MUSC, USA<br />

Resumo: Hid<strong>de</strong>n structure in geo-referenced health data is now a focus of much<br />

research. There are a number of approaches to the mo<strong>de</strong>ling of such structure,<br />

ranging from classical random effect mo<strong>de</strong>ls to full latent variable mo<strong>de</strong>ling with<br />

geo-referencing. In this talk I will focus on two examples of recent latent variable<br />

mo<strong>de</strong>l approaches. First I will consi<strong>de</strong>r the analysis of a spatially-<strong>de</strong>pen<strong>de</strong>nt<br />

environmental predictor (PM2.5 in the counties of Georgia USA) and the use of<br />

latent space-time component mixtures in two stage mo<strong>de</strong>l for health exposure risk.<br />

Second, I will consi<strong>de</strong>r spatial survival mo<strong>de</strong>ling where we have a contextual spatial<br />

effect and discrete spatial changes in regression coefficients so that different area of<br />

the study region can have different relations to the health outcome.<br />

In this approach discrete spatial prior distribution mo<strong>de</strong>ls must be consi<strong>de</strong>red and<br />

threshold CAR mo<strong>de</strong>ls are proposed as a simple approach. This is applied to prostate<br />

cancer cases from SEER registry data for the state of Louisiana USA(2000-2004).<br />

Waveletizing statistical procedures based on Fourier expansions<br />

Michel H. Montoril<br />

University of Campinas, Brazil<br />

Resumo: In this work we will discuss the use of wavelets in statistical<br />

methodologies that are based on Fourier <strong>de</strong>compositions. We briefly overview<br />

methods like classification, estimation based on biased data, additive regression and<br />

estimation of conditional <strong>de</strong>nsities. We focus on the problem of estimating<br />

regression functions of heteroscedastic mo<strong>de</strong>ls of the kind Y = f (X) + g(X), where<br />

is in<strong>de</strong>pen<strong>de</strong>nt of X, with mean 0 and variance 1. We will emphasize the estimation<br />

of the probability function in mixture regression mo<strong>de</strong>ls.<br />

Basically, there is a process Y that can be observed randomly in the time, say T,<br />

which is supported on the unit interval. For a fixed time T = t, such a process can be<br />

either a random variable (r.v.) V with probability f (t) or a r.v. W with probability 1<br />

f (t), where V and W are assumed to have known and different means. We illustrate<br />

this method by numerical simulation studies for different probability functions f.<br />

Key words: Wavelet estimation, nonparametric regression, mixture regression.<br />

Wavelet Shrinkage for Regression Mo<strong>de</strong>ls with Random<br />

Design and Correlated Errors<br />

Rogério F. Porto<br />

Banco do Brasil<br />

Resumo: Extraction of a signal in the presence of stochastic noise via wavelet<br />

shrinkage has been studied un<strong>de</strong>r assumptions that the noise is in<strong>de</strong>pen<strong>de</strong>nt and<br />

i<strong>de</strong>ntically distributed (IID) and that the samples are equispaced (evenly spaced in<br />

time). Previous work has relaxed these assumptions either to allow for correlated<br />

observations or to allow for random sampling, but very few papers have relaxed<br />

both together.<br />

In this paper we relax both assumptions by assuming the noise to be a stationary<br />

Gaussian process and by assuming a random sampling scheme dictated either by a<br />

uniform distribution or by an evenly spaced <strong>de</strong>sign subject to jittering. We show<br />

that, if the data are treated as if they were autocorrelated and equispaced, the<br />

resulting wavelet-based shrinkage estimator achieves an almost optimal<br />

convergence rate. We investigate the efficacy of the proposed methodology via<br />

simulation studies and extraction of the light curve for a variable star.<br />

Aggregated functional data mo<strong>de</strong>l for Near-Infrared<br />

Spectroscopy calibration and prediction<br />

Ronandlo Dias<br />

University of Campinas<br />

Brazil<br />

Resumo: Calibration and prediction for NIR spectroscopy data are performed based<br />

on a functional interpretation of the Beer-Lambert formula. Consi<strong>de</strong>ring that, for<br />

each chemical sample, the resulting spectrum is a continuous curve obtained as the<br />

summation of overlapped absorption spectra from each analyte plus a Gaussian<br />

error, we assume that each individual spectrum can be expan<strong>de</strong>d as a linear<br />

combination of B-splines basis. Calibration is then performed using two procedures<br />

for estimating the individual analytes curves: basis smoothing and smoothing<br />

splines.<br />

Prediction is done by minimizing the square error of prediction. To assess the<br />

variance of the predicted values, we use a leave-one-out jackknife technique.<br />

Departures from the standard error mo<strong>de</strong>ls are discussed through a simulation study,<br />

in particular, how correlated errors impact on the calibration step and consequently<br />

on the analytes’ concentration prediction. Finally, the performance of our<br />

methodology is <strong>de</strong>monstrated through the analysis of two publicly available<br />

datasets.<br />

Key words: B-splines, leave-one-out jackknife, square error of prediction<br />

Objective Bayesian inference in measurement error mo<strong>de</strong>ls<br />

Mário <strong>de</strong> Castro<br />

Ignacio Vidal<br />

Resumo: In regression analysis, when the covariates are not exactly observed,<br />

measurement error mo<strong>de</strong>ls extend the usual regression mo<strong>de</strong>ls toward a more<br />

realistic representation of the covariates. In a recent contribution, Wang &<br />

Sivaganesan (2013) propose objective priors for the parameters in normal<br />

measurement error mo<strong>de</strong>ls. The prior distributions are specified for the parameters<br />

in the regression mo<strong>de</strong>l. Posterior inference requires MCMC computations. In our<br />

approach, the regression mo<strong>de</strong>l is seen as a reparameterization of the bivariate<br />

normal distribution. We adapt the general results for objetive Bayesian inference in<br />

Berger & Sun (2008) to the regression framework. MCMC methods are not<br />

necessary at all.<br />

Bayesian analysis for zero-or-one inflated proportion<br />

data using quantile regression<br />

Bruno Santos<br />

Heleno Bolfarine<br />

Resumo: In this paper, we propose the use of Bayesian quantile regression for the<br />

analysis of proportion data. We also consi<strong>de</strong>r the case when the data presents a zero<br />

or one inflation using a two-part mo<strong>de</strong>l approach. For the latter scheme, we assume<br />

that the response variable is generated by a mixed discrete-continuous distribution<br />

with a point mass at zero or one. Quantile regression is then used to explain the<br />

conditional distribution of the continuous part between zero and one, while the<br />

mixture probability is also mo<strong>de</strong>led as a function of the covariates. We check the<br />

performance of these mo<strong>de</strong>ls with two simulation studies. We illustrate the method<br />

with data about the proportion of households with access to electricity in Brazil.<br />

Resumo: The aim of our research is to provi<strong>de</strong> algorithms of data imputation for a<br />

cyclostationary time series with heavy tails. We assume that time series of interest is<br />

K-<strong>de</strong>pen<strong>de</strong>nt but also has heavy tails. We use the multivariate t distribution with the<br />

covariance matrix Σ of or<strong>de</strong>r 2 (K − 1) × 2 (K − 1). Moreover, we assume that the<br />

number of <strong>de</strong>grees of freedom ν is fixed and 2 < ν ≤ 6. We use the periodic sequence<br />

{ct} with the period H as the periodic amplitu<strong>de</strong> imposed over the stationary<br />

background time series. We propose four imputation algorithms based on the<br />

properties of the multivariate t-distribution. Using simulations, we compare the<br />

performance of those algorithm.<br />

Resumo: We <strong>de</strong>veloped a space-time prospective surveillance method when the<br />

data are point events, monitoring if there is an emerging cluster. Typical application<br />

areas are crime or disease surveillance. At each new event, a local Knox score is<br />

calculated and spatially spread to form a stochastic surface. The surfaces are<br />

accumulated sequentially until they exceed a specified threshold, causing an alarm<br />

to go off and i<strong>de</strong>ntify the region of the probable cluster. The method requires little<br />

prior knowledge from the user and provi<strong>de</strong>s a way to i<strong>de</strong>ntify locations and time of<br />

possible clusters, through the visualization of the cumulative surface. We present a<br />

simulation study for different cluster scenarios, as well as an application to a dataset<br />

of meningitis cases in Belo Horizonte, Brazil.<br />

Melhoramentos inferenciais via bootstrap no mo<strong>de</strong>lo<br />

beta autorregressivo <strong>de</strong> médias móveis<br />

Bruna Gregory Palm<br />

Fábio M. Bayer<br />

Resumo: O presente trabalho propõe melhoramentos inferenciais em pequenas<br />

amostras para o mo<strong>de</strong>lo beta autorregressivo <strong>de</strong> médias móveis (βARMA). O<br />

mo<strong>de</strong>lo βARMA é útil para mo<strong>de</strong>lar e prever variáveis contínuas pertencentes ao<br />

intervalo (0,1), como taxas e proporções.<br />

Os procedimentos inferenciais baseados nos estimadores <strong>de</strong> máxima<br />

verossimilhança possuem boas proprieda<strong>de</strong>s assintóticas, mas em pequenas<br />

amostras po<strong>de</strong>m ter <strong>de</strong>sempenho pobre. Neste sentido, são propostas correções<br />

bootstrap dos estimadores pontuais, assim como diversas abordagens bootstrap são<br />

consi<strong>de</strong>radas para melhoramentos dos intervalos <strong>de</strong> confiança. Tais correções são<br />

avaliadas numericamente via um extensivo estudo <strong>de</strong> simulações <strong>de</strong> Monte Carlo.<br />

Os resultados numéricos evi<strong>de</strong>nciam que as inferenciais em amostras <strong>de</strong> tamanho<br />

baseadas nas correções bootstrap propostas são mais confiáveis do que quando<br />

consi<strong>de</strong>rados os estimadores <strong>de</strong> máxima verossimilhança usuais. Uma aplicação a<br />

dados reais mostra que os valores previstos da variável <strong>de</strong> interesse são mais<br />

fi<strong>de</strong>dignos quando os estimadores corrigidos são consi<strong>de</strong>rados.<br />

The Bivariate Sinh-Elliptical Distribution with Applications<br />

to Birnbaum-Saun<strong>de</strong>rs Distribution and<br />

Associated Regression and Measurement Error Mo<strong>de</strong>ls<br />

Filidor Vilca<br />

N. Balakrishnan<br />

Camila Borelli Zeller<br />

Resumo: The bivariate Sinh-Elliptical (BSE) distribution is a generalization of the<br />

well-known Rieck’s (Ph.D. thesis, Department of Mathematical Sciences, Clemson<br />

University, USA, 1989) Sinh-Normal distribution that is quite useful in Birbaum<br />

Saun<strong>de</strong>rs (BS) regression mo<strong>de</strong>l. The main aim of this paper is to <strong>de</strong>fine the BSE<br />

distribution and discuss some of its properties, such as marginal and conditional<br />

distributions and moments. In addition, the asymptotic properties of method of<br />

moments estimators are studied, extending some existing theoretical results in the<br />

literature.<br />

These results are obtained by using some known properties of the bivariate elliptical<br />

distribution. This <strong>de</strong>velopment can be viewed as a follow-up to the recent work on<br />

bivariate Birnbaum-Saun<strong>de</strong>rs distribution by Kundu et al. (J. Mult. Anal. 101: 113-<br />

125, 2010) towards some applications in the regression setup. The measurement<br />

error mo<strong>de</strong>ls are also introduced as part of the application of the results <strong>de</strong>veloped<br />

here. Finally, numerical examples using both simulated and real data are analyzed,<br />

illustrating the usefulness of the proposed methodology.<br />

Robust Bayesian mo<strong>de</strong>l selection for heavy-tailed<br />

linear regression mo<strong>de</strong>ls using finite mixtures<br />

Flávio B. Gonçalves<br />

Marcos O. Prates<br />

Victor H. Lachos<br />

Resumo: In this paper we present a novel methodology to perform Bayesian mo<strong>de</strong>l<br />

selection in linear mo<strong>de</strong>ls with heavy-tailed distributions. The new method<br />

consi<strong>de</strong>rs a finite mixture of distributions to mo<strong>de</strong>l a latent variable where each<br />

component of the mixture corresponds to one possible mo<strong>de</strong>l within the<br />

symmetrical class of normal in<strong>de</strong>pen<strong>de</strong>nt distributions. Naturally, the Gaussian<br />

mo<strong>de</strong>l is one of the possibilities. This allows a simultaneous analysis based on the<br />

posterior probability of each mo<strong>de</strong>l. Inference is performed via Markov chain<br />

Monte Carlo - a Gibbs sampler with Metropolis–Hastings steps for a class of<br />

parameters. Simulated studies highlight the advantages of this approach compared<br />

to a segregated analysis based on arbitrary mo<strong>de</strong>l selection criteria.An example with<br />

real data is also presented.<br />

Bayesian semi-parametric symmetric mo<strong>de</strong>ls for binary data<br />

Marcio Augusto Diniz<br />

Adriano Polpo<br />

Resumo: This work proposes a general Bayesian semi-parametric mo<strong>de</strong>l to binary<br />

data. It is consi<strong>de</strong>red symmetric prior probability curves as an extension for<br />

discussed i<strong>de</strong>as from [4] using the Blocked Gibbs sampler which is more general<br />

than the Polya Urn Gibbs sampler. The semi-parametric approach allows to<br />

incorporate the uncertainty around the F distribution of the latent data and mo<strong>de</strong>ling<br />

heavy-tailed or light-tailed distributions than that prior proposed. In particular, the<br />

Bayesian semi-parametric Logistic mo<strong>de</strong>l is introduced which enables one to elicit<br />

prior distributions for regression coefficients from information about odds ratios<br />

what is quite interesting in applied research. Then, this framework opens several<br />

possibilities to <strong>de</strong>al with binary data in the Bayesian perspective.<br />

Resumo: Neste trabalho estudamos a inferência estatística sob o enfoque Bayesiano<br />

nos mo<strong>de</strong>los semiparamétricos com erros nas variáveis, em que seu componente<br />

sistemático admite variáveis explicativas com e sem erro <strong>de</strong> medição, bem como a<br />

presença <strong>de</strong> um efeito não-linear aproximado através <strong>de</strong> um B-spline (veja, por<br />

exemplo, De Boor (1978)). Nestes mo<strong>de</strong>los, o componente aleatório do mo<strong>de</strong>lo<br />

consi<strong>de</strong>ra distribuições com caudas mais pesadas do que a distribuição normal<br />

multivariada, este componente é <strong>de</strong>scrito usando vetores aleatórios obtidos como<br />

misturas na escala da distribuição normal multivariada (veja, por exemplo,Andrews<br />

e Mallows, 1974), o qual proporciona flexibilida<strong>de</strong> bem como robustez frente a<br />

observações extremas na mo<strong>de</strong>lagem. Como exemplos <strong>de</strong>sta classe po<strong>de</strong>mos citar<br />

as distribuições multivariadas t-Stu<strong>de</strong>nt, slash, Laplace, hiperbólica simétrica e<br />

normal contaminada. Para obter amostras da distribuição a posteriori dos<br />

parâmetros do mo<strong>de</strong>lo propomos um algoritmo MCMC. O comportamento do<br />

algoritmo é avaliado através <strong>de</strong> um estudo <strong>de</strong> simulação.Aproposta metodológica é<br />

aplicada a um conjunto <strong>de</strong> dados reais, no qual po<strong>de</strong>mos observar que ignorar os<br />

Resumo: We present a class of randomly truncated nonlinear beta mixed-effects<br />

mo<strong>de</strong>l by consi<strong>de</strong>ring the truncation limits to be random variables and by assuming<br />

the variable of interest to follows a truncated beta distribution parametrized by a<br />

mean and a dispersion parameter. The location parameter of the responses is<br />

associated with a nonlinear continuous function of covariates and unknown<br />

parameters and with unobserved random effects. Maximum likelihood estimator of<br />

the parameters are obtained by direct maximization of the log-likelihood function<br />

via an iterative procedure and diagnostic analysis tools are consi<strong>de</strong>red to check for<br />

mo<strong>de</strong>l a<strong>de</strong>quacy. A data sets consisting of observations on soil-water retention from<br />

a soil profiles from the Buriti Vermelho River Basin database is analyzed using the<br />

Resumo: We propose in this paper a random intercept gamma mo<strong>de</strong>l in which the<br />

random effect is assumed to follow a generalized log-gamma (GLG) distribution.<br />

This flexibilization in which has been suggested by Fabio et al (2012) allows<br />

distributions for the random effect skew to the right and skew to the left and has the<br />

normal distribution as a particular case. For a particular parametrization for the GLG<br />

distribution and specifying the a<strong>de</strong>quate link function, we <strong>de</strong>rive a new continuous<br />

multivariate distribution called Gamma-GLG . Then, we obtain the moments this<br />

joint <strong>de</strong>nsity function and a Newton Raphson iterative process was <strong>de</strong>veloped for<br />

obtaining the maximum likelihood estimates for the parameters of the multivariate<br />

mo<strong>de</strong>l. Two <strong>de</strong>sviance functions and residuals analysis are proposed and an<br />

applications with real data is given for illustration.<br />

effects of the unknown QTL genotypes. We also present and compare different<br />

methods to update the QTLs location and check the performance of the<br />

methodologies on simulated and real data-sets. We observe that the data-driven<br />

reversible jump and, consequently, its convergence and increase the exploration of<br />

Mo<strong>de</strong>lo LSMIRT para varias populações<br />

Gualberto S.A. Montalvo<br />

Resumo: A multidimensional item response theory mo<strong>de</strong>l with latent linear<br />

structure for several groups is proposed. This mo<strong>de</strong>l was introduced in or<strong>de</strong>r to fit<br />

binary tests, which in turn are divi<strong>de</strong>d in several subtest and subsequently applied to<br />

different groups or populations. It is assume that each subtest measure a onedimensional<br />

latent trait (main latent trait or main ability). The main aim is to<br />

measure these latent traits. Furthermore, it is also assumed that the entire test<br />

measures a latent trait vector from tested subjects. This latent trait vector does not<br />

necessary have the same components as the main latent trait. Instead, it is supposed<br />

that the main latent traits are linear combinations of latent trait vector components.<br />

Therefore, they have a linear latent structure. Each item is assumed to belong to<br />

exactly one subtest. In this mo<strong>de</strong>l, the test dimension is <strong>de</strong>fined as the number of<br />

subtest and it may not equal the latent trait space dimension. In or<strong>de</strong>r to estimate the<br />

parameters, an augment data Gibbs sampler (DAGS) was implemented and tested in<br />

simulations. Besi<strong>de</strong>s, the mo<strong>de</strong>l was used to fit data from the ’First comparative<br />

survey on language, math and associated factors for 3rd and 4th year stu<strong>de</strong>nts<br />

(PERCE)’, which was carried out by the Latinamerican laboratory for assessment of<br />

quality of education.<br />

Gauss M. Cor<strong>de</strong>iro<br />

Ana K. Campelo<br />

Resumo: In survival analysis applications, the failure rate function may frequently<br />

present a unimodal shape. In such case, the log-normal and log-logistic distributions<br />

are used. In this paper, we shall be concerned only with parametric forms, so a<br />

location-scale regression mo<strong>de</strong>l based on the odd log-logistic Weibull distribution is<br />

proposed for mo<strong>de</strong>ling data with a <strong>de</strong>creasing, increasing, unimodal and bathtub<br />

failure rate function as an alternative to the log-Weibull regression mo<strong>de</strong>l. For<br />

censored data, we consi<strong>de</strong>r a classic method to estimate the parameters of the<br />

proposed mo<strong>de</strong>l. We <strong>de</strong>rive the appropriate matrices for assessing local influences<br />

on the parameter estimates un<strong>de</strong>r different perturbation schemes and present some<br />

ways to assess global influences. Further, for different parameter settings, sample<br />

sizes and censoring percentages, various simulations are performed. In addition, the<br />

empirical distribution of some modified residuals are displayed and compared with<br />

the standard normal distribution. These studies suggest that the residual analysis<br />

usually performed in normal linear regression mo<strong>de</strong>ls can be exten<strong>de</strong>d to a modified<br />

<strong>de</strong>viance residual in the proposed regression mo<strong>de</strong>l applied to censored data. We<br />

analyze a real data set using the log-odd log-logistic Weibull regression mo<strong>de</strong>l.<br />

Molenberghs, Verbeke, and Demétrio (2007) and Molenberghs et al. (2010), gamma<br />

and normal random effects are inclu<strong>de</strong>d in a Weibull mo<strong>de</strong>l, to account for<br />

overdispersion and between-subject effects, respectively. Unlike these authors,<br />

censoring is allowed for. Two estimation methods are presented. The partial<br />

marginalization approach to full maximum likelihood of Molenberghs et al. (2010)<br />

is contrasted with pseudo-likelihood estimation. A limited simulation study is<br />

conducted to examine the relative merits of these estimation methods. The mo<strong>de</strong>ling<br />

framework is employed to analyze data on recurrent asthma attacks in children on<br />

the one hand and on survival in cancer patients on the other.<br />

Estimação Robusta em Mo<strong>de</strong>los <strong>de</strong> Variáveis Latentes<br />

Denise Reis Costa<br />

(INEP – MEC) – Adv. Víctor Hugo Lachos Dávila<br />

Resumo: Mo<strong>de</strong>los <strong>de</strong> variáveis latentes são amplamente para mo<strong>de</strong>lar variáveis que<br />

não po<strong>de</strong>m ser medidas diretamente, conhecidas como construtos ou efeitos<br />

aleatórios. Na literatura, é muito comum verificar a utilização da distribuição<br />

normal para a mo<strong>de</strong>lagem <strong>de</strong>ssas variáveis, contudo tal suposição po<strong>de</strong> ser<br />

ina<strong>de</strong>quada, especialmente na presença <strong>de</strong> valores discrepantes.<br />

Preocupados com a sensibilida<strong>de</strong> das inferências sob a presença <strong>de</strong> potenciais<br />

pontos discrepantes ou com dados provenientes <strong>de</strong> distribuições com caudas<br />

pesadas, neste trabalho propomos métodos <strong>de</strong> inferência robusta, utilizando a<br />

distribuição t <strong>de</strong> Stu<strong>de</strong>nt multivariada, para o mo<strong>de</strong>lo linear generalizado misto para<br />

respostas binárias (GLMM) e o mo<strong>de</strong>lo <strong>de</strong> análise fatorial Tobit (TCFA) para<br />

respostas contínuas e censuradas. Para avaliação dos métodos propostos, foram<br />

realizados alguns estudos simulados, além da aplicação a conjuntos <strong>de</strong> dados reais.<br />

A Spectral Series Approach to High-Dimensional Inference<br />

Rafael Izbicki<br />

(DE – UFScar) – Adv. Ann B Lee (USA)<br />

Resumo:Akey question in mo<strong>de</strong>rn statistics is how to make efficient inferences for<br />

complex, high-dimensional data, such as images, spectra, and trajectories. While a<br />

large body of work has revolved on adapting nonparametric regression methods to<br />

high dimensions, statisticians have <strong>de</strong>voted less effort to re<strong>de</strong>signing estimators of<br />

other quantities to such settings. Some of these tasks are of key importance for the<br />

sciences; an example is the conditional <strong>de</strong>nsity estimation problem, which plays an<br />

important role in mo<strong>de</strong>rn cosmology. In this talk, we propose a nonparametric<br />

framework for estimating unknown functions in high dimensions.<br />

The basic i<strong>de</strong>a is to expand these functions in terms of a spectral basis -- the<br />

eigenfunctions of a kernel-based operator. If the kernel is appropriately chosen, then<br />

the eigenfunctions adapt to the intrinsic geometry of the data, forming an efficient<br />

Fourier-like orthogonal basis for smooth functions on the data. We show how this<br />

framework can be used for estimating several quantities, including the regression<br />

function. We provi<strong>de</strong> theoretical guarantees on the <strong>de</strong>veloped estimators and<br />

illustrate their use for several applications.<br />

Mo<strong>de</strong>los <strong>de</strong> regressão para dados censurados sob Distribuições Simétricas<br />

Aldo William Medina Garay<br />

(IMECC – Unicamp) – Adv. Heleno Bolfarine<br />

Resumo: Este trabalho tem como objetivo principal apresentar uma abordagem<br />

clássica e Bayesiana dos mo<strong>de</strong>los lineares com observações censuradas, que é uma<br />

nova área <strong>de</strong> pesquisa com gran<strong>de</strong>s possibilida<strong>de</strong>s <strong>de</strong> aplicações.Aqui, substituímos<br />

o uso convencional da distribuição normal para os erros por uma família <strong>de</strong><br />

distribuições mais flexíveis, o que nos permite lidar <strong>de</strong> forma mais a<strong>de</strong>quada com<br />

observações censuradas na presença <strong>de</strong> outliers. Esta família é obtida através <strong>de</strong> um<br />

mecanismo <strong>de</strong> fácil construção e possui como casos especiais as distribuições t <strong>de</strong><br />

Stu<strong>de</strong>nt, Pearson tipo VII, slash, normal contaminada e, obviamente, a normal.<br />

Para o caso <strong>de</strong> respostas correlacionadas e censuradas propomos um mo<strong>de</strong>lo <strong>de</strong><br />

regressão linear robusto baseado na distribuição t <strong>de</strong> Stu<strong>de</strong>nt, <strong>de</strong>senvolvendo um<br />

algoritmo tipo EM que <strong>de</strong>pen<strong>de</strong> dos dois primeiros momentos da distribuição t <strong>de</strong><br />

Exploring Multiple Evi<strong>de</strong>nces to Infer Users Location in Twitter<br />

Erica Castilho Rodrígues<br />

(ICEB-UFOP) – Adv. Renato Assunção<br />

Resumo: Online social networks are valuable sources of information to monitor<br />

real-time events, such as earthquakes and epi<strong>de</strong>mics. For this type of surveillance,<br />

users location is an essential piece of information, but a substantial number of users<br />

choose not to disclose their geographical information. However, characteristics of<br />

the users’behavior, such as the friends they associate with and the types of messages<br />

published may hint on their spatial location. In this paper, we present a method to<br />

infer the spatial location of Twitter users. Unlike the approaches proposed so far, we<br />

incorporate two sources of information to learn geographical position: the text<br />

posted by users and their friendship network. We propose a probabilistic approach<br />

that jointly mo<strong>de</strong>ls the geographical labels and Twitter texts of users organized in the<br />

form of a graph representing the friendship network.<br />

We use the Markov random field probability mo<strong>de</strong>l to represent the network and<br />

learning is carried out through a Markov chain Monte Carlo simulation technique to<br />

approximate the posterior probability distribution of the missing geographical<br />

labels. We show the accuracy of the mo<strong>de</strong>l in a large dataset of Twitter users, where<br />

the ground truth is the location given by the GPS position. The method is evaluated<br />

and compared to two baseline algorithms that employ either of these two types of<br />

information. The results obtained are significantly better than those of the baseline<br />

methods.<br />

Mo<strong>de</strong>los <strong>de</strong> regressão em Julia<br />

Luis Benites Sánchez<br />

IME-USP<br />

Resumo: O principal objetivo do workshop é oferecer a pesquisadores <strong>de</strong> todas as<br />

áreas da ciência uma introdução nos mo<strong>de</strong>los <strong>de</strong> regressão através da interação com<br />

Julia (http://www.julialang.org). O <strong>de</strong>senvolvimento <strong>de</strong> Julia começou em 2009 e<br />

uma versão <strong>de</strong> código aberto foi divulgado em fevereiro <strong>de</strong> 2012.<br />

Julia é uma linguagem dinâmica, apropriada para computação numérica e científica,<br />

com um <strong>de</strong>sempenho comparável a linguagens estáticas tradicionalmente<br />

utilizadas, tem uma sintaxe similar a do GNU Octave ou MATLAB.<br />

O workshop irá apresentar diferentes tipos mo<strong>de</strong>los <strong>de</strong> regressão usando Julia.<br />

Também sera apresentado uma introdução ao novo linguagem, assim como uma<br />

pequena comparação entre o R e Julia para conhecer algumas vantagens e<br />

<strong>de</strong>svantagen. Portanto, ao final do curso, o participante conseguirá <strong>de</strong> maneira<br />

introdutória fazer a interação Julia e os mo<strong>de</strong>los <strong>de</strong> regressão que po<strong>de</strong>rá ser<br />

<strong>de</strong>senvolvida posteriormente. Para fazer o curso é necessário conhecimento básico<br />

dos mo<strong>de</strong>los lineares.<br />
