Abstract:
|
Resource considerations often contribute to the decision to subsample nonrespondents for follow-up. For example, the resources saved by limiting the number of nonrespondents to follow may allow for a more effective, and often more expensive, mode of data collection for those subsampled. We consider weighted response rates under subsampling schemes as a measure of data quality. When subsampling is used to follow-up nonresponse, AAPOR guidelines suggest a weighted response rate that sets the nonsampled unit weights to zero and weights the subsampled unit weights by the inverse of the subsampling fraction. We also consider variations of the calculation of weighted rates when subsampling occurs and when the nonsampled units are still followed, but through a different mode. Finally, we discuss the relationship between a weighted response rate and its sampling variability.
