st: cluster analysis: differences between clusters

[Andrea Jaberg <andreauzh@gmail.com>]

Dear statalist-users

I performed optimal matching for all sequences in the dataset against
all others using -sqom- and the option -full-. Afterwards I grouped
them using cluster analysis. Now I'd like to test whether the clusters
are reliably different. My first thought was using ANOVA. However,
this seems not possible since I compared all sequences against each
other which results in a distance matrix.
What do you suggest in order to test whether the differences between
clusters are significant?

Thank you for your help
Andrea
