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 ...

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.

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.

Efficient Difference and Ratio-Type Imputation Methods under Ranked Set Sampling

open access: yesAxioms, 2023
It is well known that ranked set sampling (RSS) is more efficient than simple random sampling (SRS). Furthermore, the presence of missing data vitiates the conventional results.

RSSampling: A Pioneering Package for Ranked Set Sampling [PDF]

open access: yesThe R Journal, 2019
Ranked set sampling (RSS) is an advanced data collection method when the exact measurement of an observation is difficult and/or expensive used in a number of research areas, e.g., environment, bioinformatics, ecology, etc. In this method, random sets are drawn from a population and the units in sets are ranked with a ranking mechanism which is based ...
