Chi-Square Approximations for Exponential Parameters, Prediction Intervals and Beta Percentiles
指数分布参数、预测区间与 Beta 百分位数的卡方近似
The use of Patnaik's [28] chi-square approximation to the noncentral chi-square distribution and the Wilson-Hilferty [32] transformation of chi-square to approximate normality are explored as a simple, efficient means of finding k-order-statistic confidence bounds on parameters and reliability of the one- and two-parameter negative exponential distributions. An important implication of the results leads to obtaining simple closed-form approximations to percentiles of the…
