contrasts for Kruskal Wallis

[Richard M. Barton]

Suppose I have 4 groups, and want to compare means. I do a one-way ANOVA using Bonferroni (my choice) contrasts to get at pairwise differences.

Suppose I decide that I have non-normality problems and decide to treat dependent variable as ranks. I can do a Kruskal-Wallis test, or equivalently (I'm 99.9% sure) do a one-way ANOVA on the ranks. Can I then look at the Bonferroni pairwise tests as a reasonable follow-up for looking at where the differences lie (I'm only 75% sure I can)???

Thanks for your response.
