Practicality of Some Variations of Ranked Set Sampling

open access: yesAustrian Journal of Statistics, 2020
Judgement ranking in ranked set sampling (RSS) and its variations depends on the ability of an observer to rank a set of objects according to the study variable without doing any actual measurement.

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 ...

Estimators for the parameter mean of Morgenstern type bivariate generalized exponential distribution using ranked set sampling [PDF]

open access: yes, 2014
In situations where the sampling units in a study can be more easily ranked based on the measurement of an auxiliary variable, ranked set sampling provides unbiased estimators for the mean of a population that are more efficient than unbiased estimators ...

Estimation of Distribution Function using Percentile Ranked Set Sampling

open access: yesRevstat Statistical Journal, 2023
The estimation of distribution function has received considerable attention in the literature. Because, many practical problems involve estimation of distribution function from experimental data. Estimating the distribution function makes it possible to

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.

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.
