Who is an expert in ANCOVA?

May I know who is an expert here in ANCOVA and MANCOVA and the related post hoc analysis?

A few people have considerable expertise on those topics. But why are you asking that question instead of just asking the question that interests you?

Thanks for your response.

I already posted my queries regarding ANCOVA in the following thread:

I am waiting for the queries to be answered...

yeah well An anova test is used with three or more sets of data and is used to determine if there is a significant difference between the groups. Generally one might run just multiple t-tests but this isn't appropriate and can skew your data.

ANCOVA and multiple regression are pretty much identical. So if you know regression already, as many do, it might be easier to use that approach.

I am.

Let me stop you at your first query (in the link you provided). If the groups are equivalent at the pre-test stage, then there is no need to use ANCOVA (MACOVA). That said, just use ANOVA (MANOVA) with the usual parametric post-hoc pairwise analyses to compare groups.
