Nonparametric optimal density estimation for censored circular data

Nicolas Conanec, Claire Lacour, Thanh Mai Pham Ngoc

We consider the problem of estimating the probability density function of a circular random variable observed under censoring. To this end, we introduce a projection estimator cons…

Is model selection possible for the $ℓ_{p}$ -loss? PCO estimation for regression models

Claire Lacour, Pascal Massart, Vincent Rivoirard

This paper addresses the problem of model selection in the sequence model $Y = I^¸ + ε I^¾$ , when $I^¾$ is sub-Gaussian, for non-euclidian loss-functions. In this model, the Pena…
