When data are not normally distributed (e.g. skewed, zero-inflated, binomial, or count data) researchers are often uncertain whether it may be legitimate to use tests that assume Gaussian errors (e.g. regression, t-test, ANOVA, Gaussian mixed models), or whether one has to either model a more specific error structure or use randomization techniques.

违反正态性假设可能是两种弊端中的较小者

当数据不是正态分布时(例如偏斜,零膨胀,二项式或计数数据),研究人员通常不确定使用假定高斯误差的检验(例如回归,t检验,ANOVA,高斯混合模型)是否合法。,或者是否必须为更具体的错误结构建模或使用随机化技术。
