Hi, I have been reading up on the MULTTEST procedures available in SAS. I will be conducting multiple comparisons of 2 samples on categorical data (i.e., sample 1 vs sample 2 on yes or no responses for question #1, sample 1 vs sample 2 on yes or no responses for question #2, etc). I would like to conduct chi squares for the comparisons, but I would like to correct for multiple tests. Most of what I've read in relation to chi squares and the MULTTEST procedures is to input the raw p-values and then adjust using FDR or something else. However, I have not come across any examples of using the bootstrap procedure. Is it possible to do this at all? If I were to run the chi squares within the MULTTEST framework, would it work? I have seen a Fishers test example for permutation (so not bootstrap, but still a MULTTEST procedure), but no chi square. Any help is appreciated!

I don't know the answer, but I will point out all examples in Chapter 12 of *Multiple Comparison and Multiple Tests Using the SAS System (*which discusses using PROC MULTTEST for binary data) uses the PERMUTATION option on PROC MULTTEST for resampling. There is also a documentation example for binary data and two groups.
