On covariance estimation when nonrespondents are subsampled

Gamrot, Wojciech (author)

The phenomenon of nonresponse in a sample survey reduces the precision of parameter estimates and introduces the bias. Several procedures have been developed to compensate for these effects. An important technique is the two-phase (or double) sampling scheme which relies on subsampling the nonrespondents and re-approaching them in order to obtain the missing data. This paper focuses on the application of double sampling to estimate the finite population covariance. Two covariance estimators using combined data from the initial sample and the subsample are considered. Their properties are derived. Two special cases of the general procedure are discussed.
