Correspondence analysis and categorical conjoint measurement

Abstract

We show the equivalence between the use of correspondence analysis (CA) of concadenated tables and the application of a particular version of conjoint analysis called categorical conjoint measurement (CCM). The connection is established using canonical correlation (CC). The second part introduces the interaction e¤ects in all three variants of the analysis and shows how to pass between the results of each analysis.Correspondence analysis, conjoint analysis, canonical correlation, categorical data
