WebMost non-response weighting schemes involve ‘post-stratification ’. This is essentially a two-step procedure: (i) identify a set of ‘control totals’ for the population that the survey ought to match; (ii) calculate weights to adjust the sample totals to the control totals.

In … WebTo facilitate our discussion of the estimated-control post-stratified estimator, we label the survey requiring post-stratification as the analytic survey and the source of the control totals as the benchmark survey. In practice, more than one benchmark survey may be tapped for the control totals.
