正态分布标准差的区间估计的“优化”

The Best Interval Estimators of the Standard Deviation of a Nokmak Distribution

研究了正态总体标准差δ的区间估计,提出了在δ的全体置信水平1-a的区间估计所构成的类中,通过构造理论构造出一个“平均最短长度”δ的区间估计,其结果优于韩文俊1986年在华东工学院学报上提出的“正态总体标准差δ的区间估计方法”.

This paper research the interval estimators of standard deviation of normal distribution, construct the interval estinators of δ in the average length is shortest, which are better than that given by Han Wenjin in The interval estimators method of standard deviation of normal distribution.
