正态性检验的几种常用的方法

摘要

It is well known that the normal distribution is one of the important distribution. In statistical analysis, we usually suppose that the population submit to normal distribution. But the hypothesis needs testing. For this reason, the testing of normal distribution is significance. In this paper, we introduce several commonly methods on inspection of normal distribution. We hope these methods can give some reference for the practical and theoretical researchers interested in this issue.%正态分布是自然界中一种最常见的也是最重要的一种分布.因此,人们在实际使用统计分析时,总是乐于正态假定,但该假定是否成立,牵涉到正态性检验.在一般性的概率统计教科书中,只是把这个问题放在一般性的分布拟合下作简短处理,而这种＂万精油＂式的检验方法,对正态性检验不具有特效.鉴于此,该文从不同角度出发介绍正态性检验的几种常见的方法,并且就各种方法作了优劣比较,希望能对正态性检验感兴趣的实用和理论研究人员起到一定的参考与借鉴作用.
