The topic of this thesis is related to functional data analysis and is motivated by modern data from automobile industry. The standard functional data methods rely on the assumption that the curves are continuously observed, without error. However, in general, the real data is neither continuously nor exactly observed. Therefore, a crucial step is to recover the trajectories from noisy measurements at discrete random points. For that, we propose an original point of view: the local regularity of the process generating the curves. Thus, combining information both within and across trajectories, we propose a simple estimator for this local regularity. Given this estimate, we build a nearly optimal local polynomial smoother of the curves from ...
