Single Ordinal Correspondence Analysis with External Information

Se de ́plac ̧ant des proce ́dures non-iterative de Bo ̈ckenholt and Bo ̈ckenholt (1990) pour exe ́cuter l’analyse de correspondance avec des contraintes line ́aires, on propose une nouvelle me ́thode afin d’imposer des contraintes line ́aires a` l’approche polynomial a` l’analyse de correspondance (Beh, 1997).

Moving from the Bo ̈ckenholt and Bo ̈ckenholt (1990) non-iterative procedure for performing cor- respondence analysis with linear constraints, a new strategy is proposed in order to impose linear constraints on the polynomial approach to correspondence analysis (Beh, 1997).
