This study deals with the simultaneous nonparametric estimations of n curves or observations of a random process corrupted by noise in which sample paths belong to a nite dimension functional subspace. The estimation, by means of B-splines, leads to a new kind of functional principal components analysis. Asymptotic rates of convergence are given for the(More)
In this article, the authors examine the links between alcoholism and psychiatric disorders. They estimate that alcohol addiction is rarely a pathology that appears in an isolated fashion. North-american studies conducted within the general population (Epidemiological Catchment Area (ECA), National Comorbidity Study) have confirmed the frequent association(More)
This paper introduces a new nonparametric estimator of the regression based on penalized regression splines. Local roughness penalties that rely on local support properties of B-splines are introduced in order to deal with the spatial heterogeneity of the function to be estimated. This estimator is shown to attain optimal rates of convergence. Then its good(More)
Depression recurs in three quarters of cases; it is therefore necessary to undertake long-term studies in order to understand the clinical and epidemiological implications. Current classifications schematically distinguish depressive episodes according to their more or less permanent and complete semiological expression (at least five symptoms over at least(More)
