Figure 3.1: P value distributions. P value density distributions and quantiles f<strong>or</strong> the Bhattacharjee data as<br />

calculated by the Welch’s t–test f<strong>or</strong> each <strong>of</strong> the probe cleansing methodologies, on comparison to n<strong>or</strong>mally<br />

distributed random sampling. The top left graph presents the Gaussian kernel estimation f<strong>or</strong> the entire p<br />

value distribution, with the c<strong>or</strong>responding quantiles presented on the top right. The bottom demonstrates<br />

kernel density distributions and quantiles f<strong>or</strong> the null p values (greater than 0.05).<br />

Models and Class Predictions<br />

Figure 3.2 shows the sample class predictions when the training set values came from the<br />

Stearman experiment. The input ProbeSet lists are labeled acc<strong>or</strong>ding to the description <strong>of</strong> their<br />

generation, and include four categ<strong>or</strong>ies. The test set was the Bhattacharjee experiment (just doing<br />

two sample classes), f<strong>or</strong> each <strong>of</strong> the three classification alg<strong>or</strong>ithms: kNN, Random F<strong>or</strong>est, and<br />

LDA. The last column summarizes each selection level <strong>of</strong> the data, across the three classification<br />

alg<strong>or</strong>ithms. F<strong>or</strong> the top row <strong>of</strong> graphs in Figure 3.2, the number <strong>of</strong> input ProbeSets in each <strong>of</strong> the<br />
