| 摘 要： | 方差分析的应用条件是各总体的方差相等.因此,在方差分析之前,需进行方差齐性检验,一般用Bartlett检验.但这一方法要求分布是正态分布且计算繁琐,而用Hartleg检验和Cochran检验计算方便,方法实用;尤其Cochran 检验利用了更多的样本信息,因此显得更灵敏.对有轻微偏倚的分,Cochran检验也适用.

| Abstract: | Applying Conditions of Variance analysis are that variance of any a totality is equal to another.So,the equality examinations(Bartlett examination is adopted usually) are needed before Variance analysis,But the eistribution must be normal distribution and calculation is complilated in the method.Hartleg examination and Cochran examination can give us convenience,Forthe more,Cochran examination is better because it makes use of more sample information.At the same time,Cochran examination is adapt to slight deviational distribution. |
