Title: Variance Estimation For Calibrated Samples

Abstract:

Many of the software packages that provide survey design consistent variance estimates for complex samples do not support variance estimates when survey samples have been raked or calibrated to match known control totals. This paper compares consistent variance estimates suggested by Deville and Sarndal (1992) for calibrated samples with replication-based estimates and several convenient approximations. Biases in variance estimates are examined through a simulation study. The different techniques are also illustrated using several real-world examples.
