Orthoblique rotation is a two-stage procedure for obtaining oblique rotations used to transform vectors associated with principal component analysis or factor analysis to simple structure. The first stage will usually be an orthogonal rotation such as Varimax. The nature of the second stage will depend to some extent on the degree of obliqueness desired. A numerical example is included with two second-stage options. This technique is sometimes referred to as the Harris–Kaiser rotation.
