Abstract

This article, which will appear in the volume "Practice of Data Analysis in Economics", follows (CORR. ECO.), C.A.D. Vol X, n 2, and it takes from the latter the geometric basics and the numerical data. We define what is meant by clustering and in particular by hierarchic clustering (or the construction on a set of objects of a system of inclusion-ordered classes whose heiterogeneities increase with their sizes). An important place is devoted to agglomerative criteria and to the advantages of the inertia criterion. Using a 14 8 table, arising out of data on world phosphate trade, we illustrate the steps followed by the clustering algorithm and the output results.
