st: Cluster analysis using my own proximity matrix

["V. Sarafidis" <vs242@cam.ac.uk>]

Dear Statalisters,

I've got the following question and I would appreciate if anyone could help 
me.

Stata provides a variety of commands in order to perform cluster analysis. 
Each command allows the user to specify the "distance_option", which refers 
to the proximity measures allowed by Stata.

For example, one may use the Euclidean distance metric if dealing with 
continuous data, or the correlation coefficient proximity measure.

My question is, is it possible to use my own proximity matrix in the 
distance option? For example, if instead of using the correlation matrix, I 
wish to use a standardized correlation matrix, is this possible in Stata?

Thank you in advance for any help you may give.

Vasilis
