My team is currently split in tool usage - half of us use SPSS and half of us use SAS. There are a few processes we'd like to be able to do in SPSS. Does anyone know of an easy way to do the following?
- Factor Analysis (similar to a Varclus in SAS): we run factor analysis but are looking for something similar to the Varclus function that prevents items from loading onto multiple factors.
- Rank Order Segmentation (similar to a Fasclus in SAS): we run Cluster analysis on SPSS but often end up with a segment that's high on every input and one that is low on every input. We've been doing Fasclus in SAS but is there a way to do this in SPSS?

The SPSS mailing list (http://spssx-discussion.1045642.n5.nabble.com/)
is a lot more active than this forum these days. You might want to

My own, random comments -
I have done a lot of factor analyses of correlation matrices,
almost always for items of rating scales. My advice is not so
relevant if your best correlations are outside of the 0.35 - 0.65
After a period of experimenting, I settled on looking (rarely)
at PC; and always at FA (communalities on the diagonal),
usually with Varimax rotation. I got used to using those results,
and they served me well.
I just now looked up Varclus - it looks to me like it would
take a while to get used to using those results. Do you
have reference to someone's impressive results, from using
that? (Or Fasclus?)
