I've updated my #Stata cluster utilities

These utilities add to Stata's cluster capabilities, particularly when clustering from a distance matrix, rather than variables. Stata's "cluster stop" commands do not work in the manner you might expect with distance matrices.

The updates are mainly minor changes to keep up with newer versions of Stata. #clusteranalysis #sociology #quantmethods #datascience

I just replied to a query re optimal size of cluster solutions, a bit outside my area of expertise.

I pointed at Everitt et al as a classic: https://books.google.fr/books/about/Cluster_Analysis.html?id=htZzDGlCnQYC&redir_esc=y

Bouveyron, Celeux, Murphy & Raftery, much more up to date https://math.unice.fr/~cbouveyr/MBCbook/

My own code to estimate Calinski-Harabasz & Duda-Hart for #Stata (since Stata's built-in code doesn't work from distance matrices, only the raw data):

My main point was, however, "there is no correct answer"
