Abstract:

Multiple weight adjustments are common in surveys to account for ineligible units on a frame, nonresponse by some units, and the use of auxiliary data in estimation. A practical question is whether all of these steps need to be accounted for when estimating variances. Linearization variance estimators and related estimators in commercial software packages that use squared residuals usually account only for the last step in estimation, which is the incorporation of auxiliary data through poststratification, regression estimation, or similar methods. Replication variance estimators can implicitly account for all of the steps in estimation by repeating each adjustment separately for each replicate subsample. Through simulation, this paper studies the difference in these methods for some specific sample designs, estimators of totals, and rates of ineligibility and nonresponse.
