摘要
针对应用概率研究的需要,提出了较重尾分布的概念,以失效函数为工具,着重探讨并得到了一些利用相互比较重尾程度来确定分布族的方法.
In order to meet the needs of recent research in risk theory, the concept of the heavier-tailed distribution is been introduced,Some of its characters are given by its failure rate,Then this paper discusses a series of problems related to how to judge the distribution class and gets good results of the distribution with its the failure rate r(x) eventually decreasing to 0.
