In this talk, we present theoretical asymptotic results for the nonparametric estimation of the conditional density of a scalar response variable Y given the explanatory X taking values in a finite-dimensional space when the sample of observations is considered as a sequence of dependent random variables. As an application, using the so-called mean-shift algorithm, we provide predictive regions for bioimpedance fat-free mass for anorectic patients. This is a joint work with Pr. Najate Achamrah and Pr. Moise Coëffier (INSERM UMR 1073, Department of Clinical Nutrition of the Rouen University Hospital).
