[ 1 ] - برآوردگر جدید میانگین در طرح نمونه گیری طبقه بندی قضاوتی با مرتب کردن مشاهدات درون طبقات
Judgment post stratification is a sampling strategy which uses ranking information to give more efficient statistical inference than simple random sampling. In this paper, we introduce a new mean estimator for judgment post stratification. The estimator is obtained by using ordering observations in post strata. Our simulation results indicate that the new estimator performs better than its leadin…
[ 2 ] - Estimation of E(Y) from a Population with Known Quantiles
‎In this paper‎, ‎we consider the problem of estimating E(Y) based on a simple random sample when at least one of the population quantiles is known‎. ‎We propose a stratified estimator of E(Y)‎, ‎and show that it is strongly consistent‎. ‎We then establish the asymptotic normality of the suggested estimator‎, ‎and prove that it is…
