is it possible to conduct a (multiple-group) principle component analysis (not factor analysis) in Mplus? If yes, where can I find information on this?
Thank you!

No, Mplus does not do principal component analysis.

bad news for me;-) but thank you for your prompt reply!

Is this the reason that when I try to run the following model, I get the error: "Unknown variable(s) in an ON statement: REL"?

i s | prfsb@0 prfpm3s@1 prfpm4s@2 prfsm@3 prfpm7s@4 prfpm8s@5 prfpm9s@6 prfse@8;

rel ON prfsb prfpm3s prfpm4s prfsm prfpm7s prfpm8s prfpm9s prfse;

I would need to see the full output and your license number at to know why you get this message. It has nothing to do with principal component analysis.

Linda, in 2009 your responded to a question by saying that Mplus does not do Principal Components Analysis. Is that still true?

I didn't see it mentioned in the Mplus 7.0 Users guide.

By principal components analysis I mean extraction of orthogonal components that are weighted combinations of observed values. The components explain 100% of the observed variance, and one can say how much variance is accounted for by each component.

If Mplus does do Principal Components Analysis now, could you point me to the Mplus syntax?

Thank you very much.

Yes, this is still true. Mplus does not do Principal Component Analysis.
