Re: st: Books on clustering
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'?
