CHAPTER 16where .5 is the value of epsilon.Following is an example of how to specify an orthogonal rotation for theGEOMIN rotation and to specify an epsilon value different from thedefault:ROTATION = GEOMIN (ORTHOGONAL .5);The QUARTIMIN rotation uses the direct quartimin rotation of Jennrichand Sampson (1966). The following rotations are identical to directquartimin:CF-QUARTIMAX (OBLIQUE)CRAWFER (OBLIQUE 0)OBLIMIN (OBLIQUE 0)The rotations that begin with CF are part of the Crawford-Fergusonfamily of rotations (Browne, 2001). They are related to the CRAWFERrotation by the value of the CRAWFER parameter kappa. Following arethe values of kappa for the Crawford-Ferguson family of rotations(Browne, 2001, Table 1):CF-VARIMAX 1/pCF-QUARTIMAX 0CF-EQUAMAX m/2pCF-PARSIMAX (m-1)/(p+m-2)CF-FACPARSIM 1where p is the number of variables and m is the number of factors.The default for these rotations is oblique. Following is an example ofhow to specify an orthogonal rotation for the Crawford-Ferguson familyof rotations:ROTATION = CF-VARIMAX (ORTHOGONAL);The CRAWFER rotation is a general form of the Crawford-Fergusonfamily of rotations where kappa can be specified as a value from 0through 1. The default value of kappa is 1/p where p is the number ofvariables. Following is an example of how to specify an orthogonal538
