I have a feeling this question should be easily answered, so I suspect I might just be missing something.
On the function page of multcompare it aptly states that it performs the appropriate pairwise testing based on the stats input. But I'm trying to find what actual test is used. On the function page it keeps talking about a "hypothesis test", but I can't seem to find which actually test is being used.
In the "More about" section, it talks about t-tests, but I'm not sure if this isn't used as an example or if it means that is simply performs t-tests on the input (which would be performs on the the appropriate type of data, for instance on the ranks when using Kruskal-Wallis?).
Any help is greatly appreciated.
