Recognizing associations between large numbers of variables is a problem encountered in all the sciences. For this reason the Editor felt that the following article by Dr. Edgar E. Anderson, which appeared in the Proceedings of the National Academy of Sciences. Vol. 13, pp. 923–27, 1957, would be of interest to the readers of Technometrics. The article is republished with the kind permission of Dr. Anderson and of Dr. Wendell M. Stanley, the Editor of the Proceedings of the National Academy of Sciences.
