If you're talking about pair-wise comparisions, another option that has
been suggested here in the past is to just use the Mann-Whitney U test
(or the equivalent Wilcoxon rank-sum test).
I was wondering if anyone has a macro to perform a post hoc analysis (such
as Dunn's Test) for a Kruskal-Wallis Test. Surprisingly SPSS will perform
the KW test, but even in 11.5 does not provide a means of analysing which
pairs of groups differ significantly. I note the SPSS web site suggests
performing a series of Mann Whitney tests, but Dunn's Test (Neave and
Worthington, 1988, Distribution Free Statistics, Unwin Hyman: London)
provides a more acceptable resolution. I note that Minitab provides this
functionality since version 9 or 10.
If anyone has a macro/script to perform these multiple comparisons then it
would be greatly appreciated.
