Regression Estimator Using Double Ranked Set Sampling

open access: yesSultan Qaboos University Journal for Science, 2002
The performance of a regression estimator based on the double ranked set sample (DRSS) scheme, introduced by Al-Saleh and Al-Kadiri (2000), is investigated when the mean of the auxiliary variable X is unknown.

A Refinement of Ratio Estimation in Ranked Set Sampling and Stratified Ranked Set Sampling Approaches

open access: yesVFAST Transactions on Mathematics
Estimation of population mean is a persistent subject issue in sampling surveys and many discrete efforts have been paid by various researchers to enhance the precision of the estimates by utilizing the correlated auxiliary information. In connection with this an improved version of ratio estimator are presented in this paper under the ranked set ...

Some Shrinkage estimators based on median ranked set sampling. [PDF]

open access: yesJ Appl Stat, 2021
In this study, some shrinkage estimators using a median ranked set sample in the presence of multicollinearity were studied. Initially, we constructed the multiple regression model using median ranked set sampling.

Calibration-Based Mean Estimators under Stratified Median Ranked Set Sampling

open access: yesMathematics, 2023
Using auxiliary information, the calibration approach modifies the original design weights to enhance the mean estimates. This paper initially proposes two families of estimators based on an adaptation of the estimators presented by recent researchers ...

Variance estimation in ranked set sampling using a concomitant variable [PDF]

open access: yes, 2015
We propose a nonparametric variance estimator when ranked set sampling (RSS) and judgment post stratification (JPS) are applied by measuring a concomitant variable.

Reliability Estimation in Multistage Ranked Set Sampling

open access: yesRevstat Statistical Journal, 2017
A nonparametric reliability estimator based on multistage ranked set sampling is developed. It is shown that the estimator is unbiased and its efficiency relative to the simple random sampling rival is increasing in the number of stages.

Percentile Double Ranked Set Sampling [PDF]

open access: yesJournal of Mathematics and Statistics, 2008
Summary: The percentile double ranked set sampling (PDRSS) method is suggested for estimating the population mean. The PDRSS method is compared with simple random sampling (SRS), ranked set sampling (RSS), median ranked set sampling (MRSS) and the extreme ranked set sampling (ERSS) methods.
