20.500.12556/RUL-58645 On covariance estimation when nonrespondents are subsampled 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. true false false Fakulteta za družbene vede Angleški jezik Angleški jezik Delo ni kategorizirano 2015-07-10 18:12:21 2015-07-10 18:12:21 2022-07-04 03:42:22 0000-00-00 00:00:00 2008 0 0 Str. 95-111 No. 2 Vol. 5 2008 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 303 1854-0023 29130077 215795712 http://mrvar.fdv.uni-lj.si/pub/mz/mz5.1/gamrot.pdf 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=58656 Fakulteta za družbene vede Metodološki zvezki 0 0 0
