In this paper, a class of hybrid type estimators is proposed in estimating the finite population variance using single auxiliary variable in simple random sampling. Expressions for the bias and the mean square error (MSE) are derived up to the first order of approximation. Theoretically comparisons...

were selected with stratified random sampling from the FAHZZU patient set collected from January 2011 to December 2019 at a ratio of 4:1, where the clinical parameters between both cohorts were balanced. We repeated this procedure in a five-fold cross-validation approach, re-assigning the ...
Lifetime of individual items is a prime quality characteristic that can be treated as a continuous random variable and can be modeled by an appropriate probability distribution. In this article, double sampling plans for life tests under time censoring with a provision to draw two random samples ...
When stratified random sampling is used, these estimators are particularly efficient when the minimum and maximum values of the auxiliary variable are known. The bias and mean squared error (MSE) of the proposed classes of estimators are determined by a first-order approximation. In order to ...

random sampling of these 13 genotypes using theRfunctionrmultinom,rmultinom(n, size, prob). IfXis a random variable such thatX = {nAA,nAB,nBB}, thenX = rmultinom(1,13,nAA/13,nAB/13,nBB/13) regenerates the newborn’s genotypes subsequent to drift and from these genotypes the...
This paper presents reliability sampling plans for the Weibull distribution under Type II progressive censoring with random removals (PCR), where the number of units removed at each failure time follows a binomial distribution. To construct the sampling plans, the sample size n and the acceptance ...
