Replication Variance Estimation for Two-Phase Stratified Sampling
In two-phase sampling, the second-phase sample is often a stratified sample based on the information observed in the first-phase sample. For the total of a population characteristic, either the double-expansion estimator or the reweighted expansion estimator can be used. Given a consistent first-phase replication variance estimator, we propose a consistent variance estimator that is applicable ...
متن کاملEfficient Replication Variance Estimation for Two-phase Sampling
Variance estimation for the regression estimator for a two-phase sample is investigated. A replication variance estimator with number of replicates equal to or slightly larger than the size of the second-phase sample is developed. In surveys where the second-phase sample is much smaller than the first-phase sample, the procedure has practical advantages. The method is similar in spirit to one o...
متن کاملSuccessive Difference Replication Variance Estimation in Two-Phase Sampling∗
Successive Difference Replication (SDR) is a method of variance estimation under systematic sampling. The method has been used at the US Census Bureau for important studies including the Current Population Survey and the American Community Survey. The statistical properties of SDR are evaluated in the context of other variance estimators applicable to single-phase systematic sampling. A simulat...
متن کاملJackknife Variance Estimation for Two Samples after Imputation under Two-Phase Sampling
We propose a jackknife variance estimator for the population average from two, two-phase samples after imputation. The jackknife method has long been used to estimate and reduce bias, but has now become a valuable tool for variance estimation. We apply two different sampling methods, (simple random sampling and stratified random sampling) to derive jackknife variance estimators for the twosampl...
متن کاملTwo-phase stratified sampling designs for regional sequencing.
By systematic examination of common tag single-nucleotide polymorphisms (SNPs) across the genome, the genome-wide association study (GWAS) has proven to be a successful approach to identify genetic variants that are associated with complex diseases and traits. Although the per base pair cost of sequencing has dropped dramatically with the advent of the next-generation technologies, it may still...
