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?
