Abstract :
This note takes place in the recent infatuation for Functional
Data Analysis. Precisely, this work deals with a method able to detect
an eventual common structure between two (or more than two) groups
of curves. It is discussed how the standard approach based on factorial
analysis for comparing groups of multivariate data can be used in this
infinite dimensional framework. The potentiality of such a functional
method in terms of application is illustrated througth a spectrometric
functional dataset coming from food industry quality control.
