Abstract
Two major drawbacks of a recently proposed F-test for abstract factor analy sis (AFA) are discussed. First, heteroscedasticity in the data is not handl ed by a proper data pre-treatment. Second, negative F-values and associated degrees of freedom are encountered. It is proposed to pre-treat the data p rior to AFA. Copyright (C) 2000 John Wiley & Sons, Ltd.
