Ah...ok..now I understand.
I want to identify clusters, hence, I want to do cluster analysis.
I noticed a book called "Cluster Analysis" on the Stata site.
Would that be a good accompanying volume?

No, they aren't the same. Cluster analysis is a statistical method
(or methods) that seek to identify clusters in a dataset based on
some measure of the distance between observations. In contrast,
the analysis of clustered data (e.g., through the cluster() option
in a Stata command) can arise a wide variety of problems and refers
to known groupings in the data where often you are looking to
adjust standard errors to account for the lack of independence in
the observations within each group.

OK...I plead ignorance here.
Isn't the 'analysis of clustered data' the same as 'cluster
analysis'?
