ABSTRACT
In this chapter, I present the study of Euclidean clouds, taking into account the structures they are equipped with. The motivation is as follows: In analyse des données, the basic object of methods is a two-way table. The analysis brings out the relations between the two sets indexing the entries of the table, that is, the structures of the table. Such methods have the remarkable ability to identify these structures-this is one of their most valuable assets-but they do not take into account the structures the two sets themselves may be equipped with.
