Dunn's test is the not parametric analog of Holm-Sidak multiple t-test. When you use the Kruskal-Wallis test, you know if there is a difference among your groups, but you can't apply the KWtest for each couple because the overall error is >alpha (Bonferroni inequality). By Dunn's test you can highlight where is the difference using multiple, stepdown comparisons. The algorithm requires the Statistics Toolbox.

Hi, MATLAB's multcompare supports 'dunn-sidak' option, but that is not the same as "Dunn's test" provided here, right?
I would need a p-value for each comparison to plot it as function of an independent variable. Practically speaking I would need to convert the q-value in a p-value... Should I use a z-table?
Why? It is a metod to test GLOBAL p-value<=alpha (usually 0.05)
Hi, is there a method to extract a p-value for each comparison?
Very clear! this code is written intelligently ,thanks.
The code is writen very clearly, instructions are detailed and to the point. It did not take me more than 5 minutes to get run the test.
Very good software. I need for my original article from univesity
