shapiro 和 normaltest 可以在 python 中互换使用吗？
Can shapiro and normaltest be used interchangeably in python?
我曾经使用 scipy.stats.shapiro 来测试数据的正态性，但看起来像
scipy.stats.normaltest
也是一样。
它们可以互换使用吗？
在 this answer 中，Shapiro 似乎普遍优于 normaltest 中使用的 D'Agostino-Pearson 检验。
The ultimate reason why the Shapiro Wilk is popular has, I think, less
to do with Pubmed or NIST but rather with its excellent power in a
wide variety of situations of interest (which would in turn lead to
wider implementation and hence, popularity); it generally comes out
toward the top against a wide variety of non-normal distributions in
power comparisons with other possible choices. I wouldn't claim it's
the best possible omnibus test of normality, but it's a very solid
choice.
