6 均方的均匀性检验在合并误差项 ,尤其是在没有重复或事先没有现成的误差估计量的析因试验中 ,习惯的做法是用来自交互列的估计量。哪些列可作为误差或合并作误差 ,应由专业知识在事先作出一定的估计。这种估计假设可以用Bartlett法来检验有关均方是否均匀后作出判断〔7〕。?
Uniformity Test of 6-Means In combining error terms, especially in a factorial experiment without repeated or prior error estimators, it is customary to use estimates from interactive columns. Which columns can be used as errors or combined errors should be based on prior knowledge of certain estimates. This estimate assumes that Bartlett’s method can be used to test whether the mean square is homogeneous [7]. ?
