Adaptive density estimation: a curse of support?
Patricia Reynaud-Bouret, Vincent Rivoirard, Christine Tuleau-Malot
This paper deals with the classical problem of density estimation on the real line. Most of the existing papers devoted to minimax properties assume that the support of the underly…
Simultaneous estimation of the mean and the variance in heteroscedastic Gaussian regression
Xavier Gendre
Let be a Gaussian vector of of mean and diagonal covariance matrix . Our aim is to estimate both and the entries , for , on th…
Mixing Least-Squares Estimators when the Variance is Unknown
Christophe Giraud
We propose a procedure to handle the problem of Gaussian regression when the variance is unknown. We mix least-squares estimators from various models according to a procedure inspi…
Estimation of Gaussian graphs by model selection
Christophe Giraud
We investigate in this paper the estimation of Gaussian graphs by model selection from a non-asymptotic point of view. We start from a n-sample of a Gaussian law P_C in R^p and foc…
