摘要: 主要讨论两个服从同一指数型分布族的随机变量X和Y之间的似然比序,一般随机序和单增凸(凹)序,并得到了判别上述序成立的一些充分条件.

关键词: 似然比序, 一般随机序, 单增凸(凹)序, 似然比序, 一般随机序, 单增凸(凹)序

Abstract: This paper investigates the likelihood ratio order and the increasing convex (concave) order for exponential family of distributions. Some sufficient conditions to these orders are obatined.

Key words: usual stochastic order, increasing convex(concave) order, likelihood ratio order, usual stochastic order, increasing convex(concave) order
