Reply to Greenacre's Commentary on the Carroll-Green-Schaffer Scaling of Two-Way Correspondence Analysis Solutions

Abstract

The authors consider Greenacre's criticisms of the CGS scaling of two-way correspondence analysis. They suggest that Greenacre's indictment of this scaling approach also implies an indictment of multiple correspondence analysis interpretations—interpretations that have been made by him (and by other contributors to correspondence analysis) prior to the publication of their articles.
