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'?
