In version 9, use rotate. See [MV] factor postestimation for more details.

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

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'


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

	L = the factor loadings matrix after rotation

        A = the factor loadings matrix before rotation

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
