Analysis of the Effects of Poststratification on Errors for Estimates Using the 2003 Medical Expenditure Panel Survey Household Component. Methodology Report No. 21

摘要

This report shows the effects of post-stratification of weights for the Household Component of the 2003 Medical Expenditure Panel Survey, using various sets of marginal control totals on two types of variance estimates for a variety of national, regional, and state estimates. The variances estimation methods are a balanced repeated replication BRR method, which includes the effects of the raking on the variance, and a Taylor series method, which does not include the effects of raking. It is shown that although the estimates decrease using the BRR method when a limited set of selected controls are added to the raking process, the Taylor series estimates for the same values actually increase.
