摘　　要：本文主要研究了FGM Copula相依下随机变量二阶顺序统计量的随机比较,给出了二阶顺序统计量之间普通随机序、增凸序与增凹序关系成立的充分条件,并通过数值例子说明了主要结论。This paper investigates the stochastic comparison of second-order statistics from dependent random samples with FGM Copula. Sufficient conditions are established on the usual stochastic order, the increasing convex order and the increasing concave order for the second-order statistic. And some numerical examples are provided to illustrate the theoretical results.
