The concomitants of order statistics (COS) is a variable associated with a bivariate sample
when ordered with respect to the other variable. The distribution theory of COS is widely …

The problem of estimating the population mean is considered by McIntyre (1952). A new
sampling method is suggested, namely; ranked set sampling (RSS) as efficient method …

We introduce the successive iterations in the original FGM type bivariate-generalized
exponential distribution. Some distributional properties of concomitants of order statistics as …

The concept of ranked set sampling (RSS) is applicable whenever ranking on a set of
sampling units can be done easily using a judgment method or based on an auxiliary …

The method of maximum likelihood estimation based on ranked set sampling (RSS) and
some of its modifications is used to estimate the unknown parameters of the new Weibull …

Monitoring process variability is essential for establishing efficient process-control schemes.
In practice, when the mean levels of a parameter are constant, and the process variance (or …

In this paper, we introduce the Morgenstern type bivariate-generalized exponential
distribution. This distribution is an extension of Morgenstern type bivariate exponential …

The parameters of Downton's bivariate exponential distribution are estimated based on a
ranked set sample. Parametric and nonparametric methods are considered. The suggested …

In this work the ranked set sampling technique has been applied to estimate the scale
parameter α of a log-logistic distribution under a situation where the units in a sample can be …

We obtain unbiased estimators for a parameter of Morgenstern type bivariate gamma
distribution (MTBGD) based on the observations made on the units of the ranked set …
