In this study, we explore the effects of non-normality and heteroscedasticity when testing the hypothesis that regression lines associated with two independent groups have the same slopes. Our results indicate that some recently proposed methods that allow heteroscedasticity and perform well in extant simulation studies do not perform well for the situation at hand. Two of the methods studied here are recommended for general use.
在这项研究中，我们探讨了在检验两个独立组的回归线斜率相同的假设时，非正态性和异方差的影响。我们的结果表明，一些最近提出的允许异方差且在现有模拟研究中表现良好的方法，在当前情况下表现不佳。这里研究的两种方法被推荐用于一般用途。
