I am running a Kruskal-Wallis and selected All Pairwise Multiple Comparisons. I assume the Multiple Comparisons use the Mann-Whitney U test, but I don't see that the p values are corrected with Bonferroni. I assume, then, that I need to multiply each p value by 3 (I have three comparisons) in order to apply the Bonferroni Correction.

Stata has three built-in pairwise methods (sidak, bonferroni and scheffe) in the oneway command. Although these options are easy to use, many researchers consider the methods to be too conservative for pairwise comparisons, especially when the are many levels. voltants.com · You would not use the Bonferroni adjustment on the Kruskal-Wallis test itself.
