Stochastic Langevin Monte Carlo for (weakly) log-concave posterior distributions
Marelys Crespo Navas, Sébastien Gadat, Xavier Gendre
In this paper, we investigate a continuous time version of the Stochastic Langevin Monte Carlo method, introduced in [WT11], that incorporates a stochastic sampling step inside the…
A statistical approach for robust tolerance design
Ambre Diet, Nicolas Couellan, Xavier Gendre +1
Within an industrial manufacturing process, tolerancing is a key player. The dimensions uncertainties management starts during the design phase, with an assessment on variability o…
Maximum likelihood estimation for a bivariate Gaussian process under fixed domain asymptotics
Daira Velandia, François Bachoc, Moreno Bevilacqua +2
We consider maximum likelihood estimation with data from a bivariate Gaussian process with a separable exponential covariance model under fixed domain asymptotic. We first characte…
Minimax properties of Fréchet means of discretely sampled curves
Jérémie Bigot, Xavier Gendre
We study the problem of estimating a mean pattern from a set of similar curves in the setting where the variability in the data is due to random geometric deformations and additive…
Model selection and estimation of a component in additive regression
Xavier Gendre
Let be a random vector with mean and covariance matrix $σ^2P_n\tra{P_n}$ where is some known -matrix. We construct a statistical procedure to estima…
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…
