| 摘 要： | 用传统方法得到的两正态总体方差比的置信区间显然不是最短,因而在这个意义上讲也不是最优的。从理论上推求给出了两正态总体方差比的最优区间估计和在犯第二类错误的概率累积最小意义下的最佳双边检验。

| Abstract: | The confidence interval of variance ratio of two normal population,obtained by using traditional method,is obviously not the shortest.So it is not the best in this sense.Theoretically,we obtained the best interval estimation and the best two-side test in the sense of the least cumulative probability when making the second kind of mistakes. |
