The problem: There are no a priori groupings to run a classification on
My solution:
This is a non-R code question, so I appreciate any thoughts. I have
used pam in the cluster package proceeded by sillohouette to find the
optimum number of clusters on scaled and centered data. I have followed
this by a classification tree analysis with rpart to discern which
variables drive the clustering on the original data. Is this a sensible
approach?
many thanks,
Stephen Sefick
