| Abstract: | In a recent JMR article, the authors described and illustrated a correspondance analysis scaling that permitted both within-set and between-set squared distance comparisons. This note clarifies the realtionship between the proposed scaling and another scaling in which the diagonal matrix of singular values is applied to both X and Y coordinates. The authors examine conceptual and empirical contrasts among three alternative scalings. |
