Abstract:
|
Adjustment factors for non-response and coverage are applied to the initial weights to produce the final analytic weights. The adjustment for under- or over-coverage is applied using post-stratification. As Cochran suggested, the effectiveness of the post-stratification adjustment does completely depend on available true population parameters, or the control totals. In practice, however, the population parameters are frequently estimated directly or indirectly through modeling. This paper will discuss soundness of using estimated (as opposed to true) population parameters in post-stratification adjustment. Numerical examples will be presented.
