Abstract The standard method of creating post-strata is to define the boundaries strata on basis population characteristics auxiliary variables. Estimation treats as for stratified-sample estimation. Samples often contain empty requiring adjustment estimation procedure. To avoid post-strata, we propose using sample distribution function an variable post-strata. We show that large-sample efficie...
