PCA loadings

[Carol Gallo]

Hello everyone,

How can I generate the factorial loadings after run a PCA analyses? I was comparing the SPSS results (made by other person) with Stata ones and the rotated values/scores are different from the SPSS table called "rotated component matrix".
I also wanna to check the loadings to apply a cut-off criteria to decide which variables belong to each component.

Example:
pca [variables]
screeplot
rotate, varimax kaiser components(2)
predict [new variable], score (it produces the same values as the 'rotate' command)

That is a rather factor analysis way to treat a PCA. Why not start with factor?

I can't comment on what might differ from SPSS, as I haven't used it in this millennium, and I never rotate PCA results.

But just in case it is of interest (to anyone interested in the thread title) I will mention pcacoefsave from SSC.
