One of the difficulties inherent in the normal varimax method of the orthogonal rotation of factors, i. e., the systematic bias caused by maximization of the sum of the variances of squared normalized factor loadings by columns, is pointed out. Then, it is shown that the method we have proposed in the preceding article (1963) provides a satisfactory solution of this difficulty by showing that the result of our solution, when applied on Thurstone's PMA battery, agrees well with his subjective solution.
