The following rotations are available:
oblimin oblique oblimin family quartimin oblique targetT orthogonal target rotation targetQ oblique target rotation pstT orthogonal partially specified target rotation
pstQ oblique partially specified target rotation
oblimax oblique entropy orthogonal minimum entropy quartimax orthogonal varimax orthogonal simplimax oblique bentlerT orthogonal Bentler's invariant pattern simplicity criterion
bentlerQ oblique Bentler's invariant pattern simplicity criterion
tandemI orthogonal Tandem Criterion tandemII orthogonal Tandem Criterion geominT orthogonal geominQ oblique cfT orthogonal Crawford-Ferguson family cfQ oblique Crawford-Ferguson family infomaxT orthogonal infomaxQ oblique mccammon orthogonal McCammon minimum entropy ratio
Other rotations can be fairly easily added simply by coding a small function to calculate the rotation criterion objective function, and its gradient. A detailed example of gradient computation is in the
paper mentioned above.
