摘要
本文研究了艾拉姆咖分布的小样本区间估计和检验问题.给出了检验统计量和相应的拒绝域.比较了指数分布和艾分布的区别和差异.指出在对装备维修工时的估计时,运用艾分布可能更加精确和有意义;并运用实例分析了区间估计精度.文章对装备维修工时的估计具有一定意义.
In this paper, the problem of interval estimation and hypothesis test of Эрланга a distribution with small sample sizes was studied.The statistics of test and corresponding reject area were studied. The difference of exponential distribution and Эрланга a distribution was compared. This paper pointed out that it may be much more accurate and meaningful to estimate equipment maintenance man-hour with Эрланга distribution. The precision of interval estimate was shown by an example. This paper has great meaning in the estimation of equipment maintenance man-hour.
