Expected sample moments of concomitants of selected order statistics [PDF]
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. This task is a recurring problem in the theory of evolution strategies. Exact expressions for expected values of sums of products of concomitants of selected order statistics are derived. Then,

We introduce the generalized Farlie–Gumbel–Morgenstern (FGM) type bivariate-generalized exponential distribution. Some distributional properties of concomitants of order statistics as well as record values for this family are studied.

Ordering of Concomitants of Order Statistics, with Applications. [PDF]
Abstract : Let (Xi,Yi) be in independent rv's from some bivariate distribution. Let X(r:n) denote the rth ordered X-variate, and Y(r:n) the Y-variate paired with X(r:n). The distribution of R(r,n), the rank of Y(r:n), is applied to a matching problem. Also, it is shown that pi(1n) pi(1, n-1) ...

Multivariate order statistics via multivariate concomitants
Let \(\mathbf{X}_1,\mathbf{X}_2,\ldots,\mathbf{X}_n\) be independent and identically distributed \(k\)-dimensional random vectors. In an effort to define order statistics based on these random vectors, \textit{I. Bairamov} [ibid. 97, No. 4, 797-809 (2006; Zbl 1085.62062)] suggested to order the \(\mathbf{X}_i\)'s according to the ordered values of some

Residual and Past Entropy for Concomitants of Ordered Random Variables of Morgenstern Family
For a system, which is observed at time t, the residual and past entropies measure the uncertainty about the remaining and the past life of the distribution, respectively.

A User-Friendly Algorithm for Detecting the Influence of Background Risks on a Model
Background, or systematic, risks are integral parts of many systems and models in insurance and finance. These risks can, for example, be economic in nature, or they can carry more technical connotations, such as errors or intrusions, which could be ...

Induced Ranked Set Sampling when Units are Inducted from Several Populations
The method of ranked set sampling when units are to be inducted from several bivariate populations is introduced in this work. The best linear unbiased estimation of a common parameter of two bivariate Pareto distributions is discussed based on the n ...

ABSTRACT Background Combined oral contraceptive (COC) use in obese adult women dramatically increases the relative risk of developing a pulmonary embolism (PE). The risk of a PE in obese adolescent females taking contraceptives is currently unknown. The purpose of this investigation was to determine the effect of body mass index (BMI) and contraceptive
