Analyse de la composante chronologique dans les tableaux croisés: une approche descriptive

In this article we develop a new technique of data analysis applied to three dimensionnal tables. The main goal of that method is to describe the evolution of the statistical units with respect to the time. Inspired by the generalized principal components analysis, canonical analysis and discriminant analysis as well as the STATIS method, our technique exhibits similar statistical units provided by a classification of their trajectories.
