SUBMATRICES OF INTERASSOCIATIONS FOR SCORING INTERRELATEDNESS WITHIN MATRICES AS AN INDEX OF PSYCHOLOGICAL DISTURBANCE.

A method is given whereby a matrix of interassociations between individuals can be divided to yield a submatrix which can in turn be used to score the degree of interrelatedness of the parent matrix. The method can be appIied to determine the significance of .the difference between the inter- relatedness of two or more parent matrices. The method is applied to a small study of normal and distunbed subjects, and provides promising results.
