Abstract

This paper shows how to compute multiple correlation coefficients, partial correlation coefficients, and regression coefficients from the factorial matrix. Special emphasis is given to computation technique and to approximation formulas. The method is extremely flexible in application since it may be applied to any subset of the original set of observed variables. It is also extremely useful when many of these coefficients are desired.

Editor's Note: The reader will recognize the subject-matter treated in this article as closely allied to that of an article by Louis Guttman, “Multiple Rectilinear Prediction and the Resolution into Components,” in the June, 1940 issue of this journal. Although there is considerable overlapping in the topics considered in these two articles, it was felt that some readers would be more interested in one approach, while others would gain more from the other approach and that still others would find both presentations of value. Guttman's article is somewhat more concerned with the theoretical aspects of the problem, while Dwyer's article emphasizes the technique of computation and approximation. The manuscript for Dwyer's article was received while Guttman's article was in press. At Dwyer's request, Guttman made available to him a pre-publication copy of his manuscript so that Dwyer was able to insert in his manuscript references to the earlier one.
