Dear Stata-Listers,
I am involved in performing a cluster analysis for a matrix consisting of categorical/ binary data. My question in this respect is: When it comes to the selection of linkage rules for an agglomerative clustering approach (single linkage, complete linkage, group average, Ward�s etc.) is there any restriction with regard to the selection of the clustering approach, i.e. is it reasonable to apply the Ward�s method for categorical data as well?
Thanks a lot for your help and comments.
