Usage Note 22556: Can I do a Q-mode factor analysis?

Details

About

Rate It

All you have to do for a Q mode principal component analysis is to transpose the data set. If any standardization is required to make the variables comparable, it should be done with PROC STANDARD before transposing, and you may want to use the COV and/or NOINT options in FACTOR/PRINCOMP depending on the purpose of the analysis. Q mode common factor analysis makes no statistical sense.
