紧急求助，什么是scheffe法和事后检定，在什么书上有介绍

micro@

Books on multiple testing in linear models.

Scheffe controls error rate for ALL possible linear contrasts.

So it is conservative, but general.

I don't think it matters for post-hoc or ad-hoc, if you use Scheffe's.

But it matters for other methods.

多重比较问题。

如果要进行多重比较，一般不建议事后检验，因为那样会改变检验水平。
