## How can I obtain the correlation between the factors after an oblique rotation?

 Title Correlations between factors after oblique rotation Authors Gene Fisher, Department of Sociology, University of Massachusetts Kenneth Higbee, StataCorp

After factor analysis (the factor command), you can obtain several matrices using the matrix get command (see [P] matrix get). These matrices include

        Ld    factor loadings
Ev    eigenvalues
Psi   uniqueness
Co    correlation matrix
SD    standard deviations
Mean  means


In addition after rotation (the rotate command), you can obtain

        L     factor loadings after rotation


The correlation matrix of the rotated factors can be computed as

        Phi = T*T'


where

        T = inverse(L'*L) * L'*A



So to obtain the correlation matrix of the rotated factors you

 . factor ...
. rotate ...

. mat L = get(L)
. mat T = syminv(L'*L)*L'*get(Ld)
. mat Phi = T*T'
. mat list Phi
