Abstract

Oblimin rotation is a general form for obtaining oblique rotations used to transform vectors associated with principal component analysis or factor analysis to simple structure. Oblimin is similar to the Orthomax rotation procedures used in orthogonal rotation in that it, too, includes an arbitrary constant used to obtain different rotational properties. A numerical example is included. While most orthogonal rotations use some form of Orthomax rotation, this is no longer the case with Oblimin rotation for the oblique case.
