您要查找的是不是:
- 等方差性Bartlett检验Bartlett's test for equal variance
- 如同上面的“等方差”情况,可以使用此t-检验来确定两个样本是否来自具有相同总体平均值的分布。As with the preceding Equal Variances case, you can use this t-Test to determine whether the two samples are likely to have come from distributions with equal population means.
- 等方差性equal variance
- 等方差线是指提供相同投资组合方差的曲线。不同方差的曲线就构成了方差曲线族。An isovariance curve provides a locus of portfolios that provide the same portfolio variance. A family of isovariance curves, each containing a different level of portfolio variance, can be obtained.

- 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;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.
