En présence d'un échantillon i.i.d. d'une variable aléatoire corrumpue Y=X+ε, avec X et ε indépendants. Nous proposons une méthode basée sur la validation-croisée, pour choisir la largeur de la fenêtre de l'estimateur à noyau de la densité de X. L'optimalité asymptotique de la méthode proposée est établie.
Assume we have i.i.d. replications from the corrupted random variable Y=X+ε, where X and ε are independent. We propose a data-driven bandwidth based on cross-validation ideas, for the kernel deconvolution estimator of the density of X. The proposed method is shown to be asymptotically optimal.
