On Regression Estimators Using Extreme Ranked Set Samples

Sultan Qaboos University Journal for Science, 2004
Regression is used to estimate the population mean of the response variable, , in the two cases where the population mean of the concomitant (auxiliary) variable, , is known and where it is unknown. In the latter case, a double sampling method is used to

Ranked Set Two-Sample Permutation Test

Statistica, 2017
In this paper, ranked set two-sample permutation test of comparing two-independent groups in terms of some measure of location is presented. Three test statistics are proposed. The statistical power of these new test statistics are evaluated numerically.

Composite Estimators for the Population Mean Under Ranked Set Sampling

Mathematics
Ranked Set Sampling (RSS) is an effective sampling technique, particularly when precise measurement of the study variable is costly or time-consuming, but ranking the units is relatively easy.

Bayesian mixture modelling with ranked set samples

Statistics in Medicine
We consider the Bayesian estimation of the parameters of a finite mixture model from independent order statistics arising from imperfect ranked set sampling designs. As a cost‐effective method, ranked set sampling enables us to incorporate easily attainable characteristics, as ranking information, into data collection and Bayesian estimation. To handle

On indirect estimation of small area parameters under ranked set sampling

Alexandria Engineering Journal
In investigations of domains under post-stratified random sampling, it is difficult to get an acceptable precision for domain-specific estimates due to low sample sizes. Small area estimate, a popular technique that has been widely used over the past few

Estimation of Variance of Normal Distribution using Ranked Set Sampling

پژوهش‌های ریاضی, 2019
Introduction     In some biological, environmental or ecological studies, there are situations in which obtaining exact measurements of sample units are much harder than ranking them in a set of small size without referring to their precise values.
