Factor Analysis: SAS vs SPSS

mcstagger

Hello all!

I am trying to further merge my SPSS analyses over to JMP. I am currently working on a Factor Analysis and I am seeing some differences that I need to understand better.

I am looking for documentation on how SAS's FA differs from SPSS's. What I am seeing in a PCA are completely different groupings even though the Communalities roughly match up between the two platforms. Google is failing me a bit on this one so I am hoping the hive mind here may be able to point me in a more fruitful direction.

I haven't used SPSS for Factor Analysis, so I don't have direct experience with the differences between SAS and SPSS. However, the presentation linked below seems to outline a number of similarities and differences between SAS and SPSS for factor analysis:

Hope that helps somewhat!
