一类分布及相关问题探讨

A Kind of Distribution and the Reated Problems

Pitman准则的研究是近年来统计理论中参数估计研究的一个热点 ,已有相当多的文献出现。笔者建立的一类分布 Jm,δ ,μ正是适应这种研究的需要而产生的 ,借助于这一分布 ,可以方便地对正态假定下的线性估计确定Pitman准则下的序关系。

The researches on the parameter estimate of statistic theory are recently focusing on the Pitman criterion.There have been quite a number of literature published.In this paper,a kind of distribution J m,δ,μ has been established to fit the needs of the above researches.Using this distribution,it is conveniently to discuss the order relation between estimates of normal school by the Pitman criterion.
