THE PROCRUSTES CLASS OF FACTOR-ANALYTIC TRANSFORMATIONS

The Procrustes method of deriving a reference vector structure from a principal-axes factor matrix is shown to be a class of solutions all of which obtain a transformation matrix which “rotates” the principal-axes matrix as close as possible to some desired matrix H. Various factor transformation methods, such as Promax, eigenvector rotation, as well as the classical Procrustes, differ chiefly in their rationale and method of generating H.
