Abstract
In this work, we consider two sets of dependent variables and , where and , for , which are coupled by Archimedean copulas having different generators. Also, let and be two non-negative integer-valued random variables, independent of s and s, respectively. We then establish different inequalities between two extremes, namely, and and and , in terms of the usual stochastic, star, Lorenz, hazard rate, reversed hazard rate and dispersive orders. We also establish some ordering results between and and and in terms of the usual stochastic order. Several examples and counterexamples are presented for illustrating all the results established here. Some of the results here extend the existing results of Barmalzan et al. (2020).
