Ranked set sampling is used when the measurement or quantification of units of the variable under study is difficult but the ranking of units of sets of small sizes can be done easily by an inexpensive method. Dell and Clutter (1972) showed that the sample mean based on ranked set sample is more efficient than the sample mean based on simple random sample with replacement sampling procedure for...

We consider estimation of quantiles when data are generated from ranked set sampling. A new estimator is proposed and is shown to have a smaller asymptotic variance for all distributions. It is also shown that the optimal sampling strategy is to select observations with one fixed rank from different ranked sets. Both the optimal rank and the relative efficiency gain with respect to simple rando...

In this paper, a new Single Sampling Plan in light of ranked data scheme is proposed. Two main prerequisites are considered for the plan: The lifetime test units assumed to follow Logistic distribution, and selected by using set sampling from large lot. distribution function characterization under derived assuming that size known; minimum number cycle consequently sample necessary ensure operat...

The basic assumption of the parametric control charts is that underlying process follows specific distribution. appropriateness questionable when different industrial applications do not support this desired assumption. Recently, nonparametric have been introduced to overcome deficiency charts. Nonparametric same in-control run-length characteristics for all continuous distributions and are rob...

Using auxiliary information, the calibration approach modifies original design weights to enhance mean estimates. This paper initially proposes two families of estimators based on an adaptation presented by recent researchers, and then, it presents a new family with set some constraints under stratified median ranked sampling (MRSS). The result has also been implemented situation two-stage To b...

In this paper, the derivation of likelihood function for parameter estimation based on double ranked set sampling (DRSS) designs used by Sabry el.al.; (2019) parameters power generalized Weibull distribution is considered. The developed then exponential Pareto parameters. maximum estimators (MLEs) are investigated and compared to corresponding ones simple random (SRS) (RSS) designs. A Monte Car...
