ORTHPROC program information and links
I'm not crazy about orthogonal solutions in factor analysis but they
have their uses, and sometimes they are simply what you find in the
literature, so with that in mind, here is a program to compare
orthogonal solutions "orthogonally." (Alternatively, you can compare
orthogonal solutions after rotating them obliquely using my COMPARE program.) -JSF

procrustes factor matching via Cliff's (1966) method [computer
software]. Available from: http://swppr.org.
ORTHPROC rotates orthogonal factor matrices to maximum congruence,
subject to the restriction of orthogonality of the solution. Following
the rotations congruence coefficients and root-mean-square measures are
computed for the transformed loadings.
