Variance estimation of medians in stratified samples [electronic resource] / by J. Kovar. [Ottawa] : Statistics Canada, 1987. 13 p. Working paper ; 87-4 Digitized edition from print [produced by Statistics Canada]. "Working paper No. BSMD-87-004E." "March 1987." Includes bibliographic references. "This paper addresses the problem of estimating the precision of the estimates of quantiles in stratified samples. Resampling methods, including the balanced half-sample replication and the bootstrap are compared to a method based on Woodruff confidence intervals. The jackknife variance estimator is shown to be inconsistent. Results of empirical studies on bias and stability of these variance estimators are presented and confidence interval coverage probabilities as well as lengths are reported"--Abstract.
