%X 本文研究了Fisher-Z分布次序统计量的随机比较问题.利用Beta随机变量的性质以及比例风险率模型的次序统计量随机比较的结论,获得了Fisher-Z分布次序统计量向量的普通多元随机序的比较,推广了文献中的相关结果.<br>In this paper, we study the stochastic comparisons of order statistics from heterogeneous Fisher-Z components. By the properties of Beta random variable and the known stochastic comparative results of order statistics from proportional hazard rates models, we obtain the stochastic comparisons of order statistics from heterogeneous Fisher-Z components with respect to the usual multivariate stochastic order, which generalize some results in literatures
