FACTOR TRANSFORMATION METHODS
D. N. Lawley, Annette E. Maxwell · British Journal of Statistical Psychology · 1964
Methods are described for transforming factors in such a way that the final loadings are in reasonable conformity with a given pattern in which some of the elements are postulated to be zero. A distinction is made between factors which, in their transformed state, are (i) correlated and (ii) uncorrelated. The methods are illustrated by numerical examples.
