A method for factoring large numbers of items

摘要: The computation of intercorrelation matrices involving large numbers variables and the subsequent factoring these present a formidable task. A method for estimating factor loadings without computing matrix is developed. estimation procedure derived from theoretical model which shown to be special case multiple-group centroid factoring. Empirical checks have indicated that model, even though it makes some stringent assumptions, can applied variety found in psychological problems. It has been particularly useful test items.
