ENTROMIN AND ENTROMAX: CRITERIA FOR FACTOR ROTATION BASED ON ENTROPY

Abstract

This paper proposes ENTROMIN and ENTROMAX criteria based on entropy for orthogonal factor rotation and their computational algorithms. One of the main advantages of themethods is that they can be used for assessing and comparing the parsimony of factor structuresby the measure of relative entropy. Illustrative analyses are presented to examine the availability of the proposed methods. Results of applications of the methods are compared with resultsobtained using principal factor solution followed by VARIMAX rotation.
