IPA 2009 Multi-beneficiary StatisticalCooperation Programmethe above resources (BS or SBS). The survey does not cover all enterprises of theBR, so indirect methods are used for the evaluation of their indicators.For the part of business register not covered by surveys, some indicators based onadministrative data sources are estimated, such as file of VAT by the taxadministration (this file provides only data on turnover). Indicators like the numberof enterprises and the number of employees are calculated on the basis of BR. Otherindicators are estimated through imputation.Imputation of indicator’s production is calculated by multiplying the turnover of theVAT with the ratio estimated by the production and turnover of enterprises fromtable BS and SBS (enterprises with the same legal status and in the same economicactivity). That gives an estimate of the production of enterprises that are in the VATfile.Imputation of those indicators is realized as follows:Pr oduction _ BS & SBS _ iPr oduction _ VAT _ i Turnover _ VAT _ i *Turnover _ BS & SBS _ iInterm_Consump_BS & SBS _ iInterm_Consump_VAT _ i Production_VAT _ i Production_BS & SBS_iGross _ Value _ Added _ VAT _ i Pr oduction _ VAT _ i Interm _ Consump _ VAT _ ii Large;Medium;SmallThe following table represents indicators of enterprises from VAT for the branch ofconstruction.15Table 3.8: Indicators estimated with data from VAT 3 file in the year 2006.In Million LEKIndicators Nr of Nr of Turnover Production Intermediate GrossEnterp EmployeesConsumption ValueStrata riseAddedLarge 1 59 8,980 9,118 6,730 2,389Medium 33 283 983,294 1,001,087 716,049 285,037Small 142 370 1,881,914 1,896,210 1,385,430 510,780Total 176 712 2,874,188 2,906,415 2,108,209 798,2063 blue colors used to distinguish those data which are estimated by the imputationmethod42/236

IPA 2009 Multi-beneficiary StatisticalCooperation ProgrammeAt the end of this stage summary of data from three sources BS, SBS and VAT (tableBS and SBS and VAT) is carried out. For example, the number of enterprises can besummarized as follows:No _ ofEnterprises _ i No _ ofEnterprises _ BS & SBS _ i No _ ofEnterprises _ VATi Large;Medium;Small16Table 3.9: Indicators estimated with integrated data from BS and SBS andVAT in the year 2006.In Million LEKIndicators Nr of Nr of Turnover Production Intermediate GrossEnterpr EmployeeConsumption ValueStrata ise sAddedLarge 45 3,852 14,187,134 14,405,913 10,632,352 3,773,561Medium 719 9,253 33,825,945 34,438,028 24,632,555 9,805,473Small 820 2,189 8,352,256 8,415,704 6,148,776 2,266,928Total 1,584 15,294 56,365,335 57,259,645 41,413,683 15,845,962A separate estimate is made for the enterprise recorded on the BR but for which dataaren’t available from any of these three sources (these are considered “missing”enterprises). From BR, the “missing”, only the number of enterprises and the numberof employees are directly evaluated. To make estimation of other indicators theirimputation is done given the data that we know or estimate in the previous stage.The following procedure was chosen for carrying out imputations:- The number of employees insured through BR;- The units in the register are stratified into three strata: small enterprises with1-4 employees, medium enterprises with 5-49 employees and largeenterprises with 50 or more employees;- Performed numerical evaluation of the enterprise involved in missingenterprise (estimate indicator for number of enterprise);- At the end, estimate indicators that cannot be directly evaluated. Theirestimation would be through imputation:43/236
