Résumé
Abstract

Cette Note a pour objet de construire un test dʼadditivité de la partie non linéaire du modèle partiellement linéaire. Plus précisément, en considérant un modèle de la forme $Y = Z^{⊤} β + m (X) + ε$ , où $m (X)$ correspond à la partie non linéaire et X est un vecteur aléatoire prenant ses valeurs dans $R^{d}$ , il sʼagit alors de construire une procédure de test permettant de vérifier si lʼhypothèse selon laquelle la fonction m peut sʼécrire sous la forme $m (x) = \sum_{l = 1}^{d} m_{l} (x_{l})$ , où les $m_{i}$ sont des fonctions définie sur $R$ , est vraisemblable.

Our aim in this Note is to build an additivity test relative to the nonlinear part of the partially linear model. More precisely, considering the model of the form $Y = Z^{⊤} β + m (X) + ε$ , where $m (X)$ stands as the nonlinear part and X is a random vector taking values in the space $R^{d}$ , our goal is to construct a testing procedure that allows us to test the validity of the hypothesis according to which the function m may be written with the shape $m (x) = \sum_{l = 1}^{d} m_{l} (x_{l})$ , where the $m_{l}$ ʼs are functions defined on $R$ .
