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.
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.
