Discriminating analysis of qualitative data inputs (French)
Classical methods of analysis are ill-suited to dealing with this type of data, so that a new family of methods has recently been developed under impetus from C. Hayashu, J. de Leeuw, G. Saporta, M. Tenenhaus and F.W. Young. They attempt, by optimal quantification subject to inherent constraints, to determine the "best" factor analysis, the "best" regression procedure, and so on. This paper is concerned with a decisional (l.e. guiding selection of explanatory variables) method put forward by G. Saporta.
