Abstract
Given a large scale two-way contingency table, the problem of its interpretation is examined. In this paper, an interpretation consists of a reduced table which summarizes the information contained in the initial tableo Each set partition allows one to reduce the initial table, by adding the rows or columns relative to the elements which belong to the same class. A class hierarchy 01 a set defines a set of partitions, by considering the different levels 01 the hierarchy. As an example, the steps in the REDTAB program running process are presented with the tables of the output file.
