Wilcoxon signed rank test using ranked-set sample
Korean Journal of Computational & Applied Mathematics, 1996Ranked-set sampling is useful when measurements are destructive or costly to obtain but ranking of the observations is relatively easy. The Wilcoxon signed rank test statistic based on the ranked-set sample is considered. We compared the asymptotic relative efficiencies of the RSS Wilcoxon signed rank test statistic with respect to the SRS Wilcoxon ...

Non-Parametric Selected Ranked Set Sampling
Biometrical Journal, 2001Summary: A nonparametric selected ranked set sampling is suggested. The estimator of population mean based on the new approach is compared with that using the simple random sampling (SRS), the ranked set sampling (RSS) and the median ranked set sampling (MRSS) methods.

Mixed ranked set sampling design
Journal of Applied Statistics, 2014The main focus of agricultural, ecological and environmental studies is to develop well designed, cost-effective and efficient sampling designs. Ranked set sampling (RSS) is one method that leads to accomplish such objectives by incorporating expert knowledge to its advantage.

A ranked-set sample signed-rank statistic
Journal of Nonparametric Statistics, 1998A procedure analogous to the Wilcoxon signed-rank test is developed for settings in which ranked-set samples are used in place of simple random samples. The ranked-set sample statistic is shown to be distribution-free and to have a symmetric null distribution. The statistic is a linear combination of U-statistics, so U-statistics results can be used to

Robust extreme ranked set sampling
Journal of Statistical Computation and Simulation, 2009In this paper, a robust extreme ranked set sampling (RERSS) procedure for estimating the population mean is introduced. It is shown that the proposed method gives an unbiased estimator with smaller variance, provided the underlying distribution is symmetric.

Summary: Stratified simple random sampling (SSRS) is used in certain types of surveys because it combines the conceptual simplicity of simple random sampling (SRS) with potentially significant gains in efficiency. It is a convenient technique to use whenever we wish to ensure that our sample is representative of the population and also to obtain ...
