利用非参数统计中的U统计量构造了检验两个总体方差是否相等的方法.与F检验法相比,该方法不仅适用范围更加广泛,且其渐近相对效率为1.
Based on the U-statistics,a new method for testing the equality of variances of two populations is constructed.Compared to the F-testing method,it is not only applicable to more general situations,but also its asymptotic relative efficiency is equal to 1.
