How to plot dendrogram and stars for pair-wise significance levels in anova?

4 views (last 30 days)
In publications with ANOVA results, often one can find box plots with a dendrogram on top and 1 to 4 stars giving the significance levels of all pairwise comparisons: p-value ≤ 0.05 -> * 0.01 -> ** 0.001 -> *** 0.0001 -> ****
Is there a script to do this in matlab?

Something like this?
load carbig
X = [MPG Acceleration Weight Displacement];
[d,p,stats] = manova1(X,Origin);
Check documentation for use manovacluster

Dear Alberto, thanks for your answer. It comes close! The height of the split points should be uniform (just to indicate grouping), and there should be a number of stars over the top split, indicating the significance. I'll see if I find an example in existing publications.
