摘　　要：研究了双参数指数分布的区间估计方法.首先讨论了当其中一参数为已知,而另一参数未知时,双参数指数分布尺度参数基于选定枢轴变量的最短区间估计方法;然后讨论了两参数均未知的情况下,参数的最短置信区间估计方法.The method of interval estimate on exponential distribution with two-parameter is studied.Firstly,the shortest confidence interval of scale parameter based on chosen pivot variables for exponential distribution with two-parameter is studied on condition that the other parameter has been known.Then the methods of the shortest confidence interval of scale parameters based on chosen pivot variables for two-parameter exponential distribution are discussed under the condition that no parameter has been known.

关 键 词：双参数指数分布 区间估计 最短置信区间
