Introduction à la classification ascendante hiérarchique d'après un exemple de données économiques

Authors(s) and Affiliation(s)



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.
