In this paper we prove some stochastic comparisons results for progressive type II censored order statistics. The problem of stochastically comparing concomitants of the two progressive type II censored order statistics with possibly different schemes, under different kinds of dependence between X and Y is considered and it is proved that if Y is stochastically increasing (decreasing) in X, ...

Abstract In this paper, a measure of extropy is obtained for concomitants m-generalized order statistics in the Morgenstern family. The cumulative residual (CREX) and negative (NCEX) are presented r th concomitant statistics. addition, problem estimating CREX NCEX studied utilizing empirical method Some applications these results given record values.

In this paper, we introduce the Morgenstern type bivariate generalized exponential distribution. This distribution is an extension of Morgenstern type bivariate exponential distribution and the marginal distributions are generalized exponential distribution. We study some properties of this bivariate distribution. Also, some distributional properties of concomitants of order statistics as well ...

In this paper, the task of determining expected values of sample moments, where the sample members have been selected based on noisy information, is considered. Exact expressions for expected values of sums of products of concomitants of selected order statistics are derived. Then, using Edgeworth and Cornish-Fisher approximations, explicit results that depend on coefficients that can be determ...

In this paper we have obtained the distribution of concomitant of order statistics for Bivariate Pseudo-Exponential distribution. The expression for moments has also been obtained. We have found that only the fractional moments of the distribution exist. The tables for survival function and hazard function has also been obtained.
