指数分布场合下基于分组数据和双向删失数据的区间估计

CONFIDENCE INTERVALS FOR MEAN LIFE BASED ON GROUPED DATA AND BINARY DATA UNDER EXPONENTIAL DISTRIBUTION

当寿命分布是指数分布时本文给出了基于分组数据和双向删失数据求平均寿命的近似区间估计方法,所给方法的计算是简单的.

In this paper, we give confidence intervals for mean life θ based on grouped data and binary data under exponential distribution. The approximated confidence interval is ( 2rθ/x_((a/2)~2(2r+2)), 2rθ/x_((1-a/2)~2(2r+2))where θ is MLE,r is the failure number.
