Abstract:

Replication methods are used frequently to construct variance estimators under complex sampling designs. We develop a replication variance estimator for the situation in which some of the sample elements are unobserved and their information is imputed. The method relies on fractional hot-deck imputation and adjusts the variance replicates to account for the imputation mechanism. The properties of the method are discussed.
