The two options for cluster analysis appear to be Source and Node. Is it possible to do a cluster analysis for sources that I've grouped using case classification attributes?
For example, let's say School 1, School 2, School 3, ... n each have a # of sources (records, interviews, etc.). I made these sources into cases, then assigned the names of schools as case classification attributes (so School 1 is the attribute value for all its sources and so forth). I want to see which schools (= its collection of sources) have similar coding.
