A short method of factor analysis

Abstract

"Occasions arise where it is desirable to apply factor analytic techniques, but the exploratory nature of the work and the time available may not justify a complete centroid analysis. A diagonal method, modified by using reliabilities instead of guessed communalities in the diagonal cells, is suggested as a statisfactory and economical substitute for the complete centroid solution under certain conditions. The results of an empirical comparison of this method with the complete centroid method on one correlation matrix show that the two agreed fairly closely upon most of the factors obtained."
