Multiple-Factor Analysis: A Development and Expansion of The Vectors of Mind

xix, 535 pp. 8vo. "Correcting much of the misinterpretation which arose from the lack of complete exposition in Vectors of Mind, Dr. Thurstone here supports the theorems introduced in the earlier book and adds new theory on the influence of selection and the second-order domain. Simple structure, communality, and the oblique reference frame, as well as other concepts, are expanded and explained. New factorial methods are presented which enable individuals to handle rotational problems and factoring problems."
