Statistical mathematics

Participant : Matthieu Lerasle.

In collaboration with R. Diel, Matthieu Lerasle published an article on nonparametric estimation for random walks in random environments. They proposed a non-parametric approach for estimating the distribution of the environment from the observation of one trajectory of a random walk in it. They obtained risk bounds in sup-norm for the cumulative distribution function of the environment.
