  • Ghattas, B.

Abstract

CART est une des rares techniques non parametriques permettant d'etablir une hierarchie des variables explicatives. Dans cet article nous decrivons le calcul de l'importance des variables a partir d'un arbre de regression et nous analysons un exemple de hierarchie de variables explicatives utilisees dans le cadre de la prevision des pics d'ozone dans les Bouches-du-Rhone.
