A single plane method of rotation

The method of rotation described here is applied to one hyperplane at a time. The method seems to be simple and quite effective and it can be applied by a relatively inexperienced computer. The method does not postulate a positive manifold, and hence it is applicable also to bipolar factors.The author wishes to express his indebtedness to the Social Science Research Committee of The University of Chicago for support of the Psychometric Laboratory and these factorial investigations.
