I would like to ask the list a question which seems to subtle to yield
to Google. Suppose we wish to cluster multivariate data that are already
classified. Certainly data in the same group of the classification
should be in the same cluster but we may like to find a coarser
clustering in which some of the classification groups are merged.
I can think of a few things that might be done but I wonder if anyone
can point me to papers on such questions - theoretical or applied?
Cheers, Murray
