摘要:

给出一种利用非参数统计中U统计量构造检验单个总体方差差异的方法, 与χ2检验法相比, 该方法不仅适用于更宽泛的场合, 而且其渐近相对效率为1.

关键词: U统计量, 方差检验, 渐近正态性, 渐近相对效率

Abstract:

A method about testing variance differences of a single population was constructed based on Ustatistics. This method, compared with the χ2 testing, can be applied to more general situations, and its asymptotic relative efficiency is 1.

Key words: Ustatistics, variance testing, asymptotic normality, asymptotic relative efficiency
