I would like to cluster a fairly large number of observation based on
presence of cases for a number of variables. Hierarchical clustering
with e.g. jaccard's similarity would be possible for a relatively
small data set due to the size of the similarity matrix (n x n). Is it
possible to use stata's cluster function with similarity matrices in a
long rather than wide format?
