Résumé
Abstract

Soit ${(X_{i}, Y_{i})}_{i = 1, \dots, n}$ une suite de vecteurs aléatoires, fortement mélangeants, à valeurs dans $F \times R$ , où $F$ est un espace de Hilbert. Dans cette note, nous nous intéressons au problème d'estimation locale linéaire de la distribution conditionnelle de $Y_{i}$ sachant $X_{i}$ . Les objectifs principaux de cette note sont donc (i) de construire un estimateur local linéaire rapide, en introduisant la technique des k plus proches voisins, de la distribution conditionnelle et (ii) de prouver sa consistance forte dans le cadre des séries temporelles conditionnelles.

Let ${(X_{i}, Y_{i})}_{i = 1, \dots, n}$ be a sequence of strongly mixing random vectors valued in $F \times R$ , where $F$ is a Hilbert space. This note deals with the problem of the local linear estimation of the conditional cumulative distribution function of $Y_{i}$ given $X_{i}$ . Then, the main goals of this note are (i) to construct a fast kNN local linear estimate of the conditional distribution function, and (ii) to prove its strong consistency in the functional time series analysis situation.
