A joint detection-estimation framework for analysing within-subject fMRI data
Vincent, Thomas; Risser, Laurent; Ciuciu, Pierre; … - Université Paris-Dauphine (Paris IX) - 2010
Abstract: In this paper, we review classical and advanced methodologies for analysing within-subject functional Magnetic Resonance Imaging (fMRI) data. Such data are usually acquired during sensory or cognitive experiments that aims at stimulating the subject in the scanner and eliciting evoked...

On Bayesian Data Analysis
Rousseau, Judith; Robert, Christian P. - Université Paris-Dauphine (Paris IX) - 2010
This introduction to Bayesian statistics presents the main concepts as well as the principal reasons advocated in favour of a Bayesian modelling. We cover the various approaches to prior determination as well as the basis asymptotic arguments in favour of using Bayes estimators. The testing...

Bayesian Inference for Mixtures of Stable Distributions
Casarin, Roberto - Université Paris-Dauphine (Paris IX) - 2003
In many different fields such as hydrology, telecommunications, physics of condensed matter and finance, the gaussian model results unsatisfactory and reveals difficulties in fitting data with skewness, heavy tails and multimodality. The use of stable distributions allows for modelling skewness...

Bayesian computation for statistical models with intractable normalizing constants
Atchade, Yves; Lartillot, Nicolas; Robert, Christian P. - Université Paris-Dauphine (Paris IX) - 2012
This paper deals with some computational aspects in the Bayesian analysis of statistical models with intractable normalizing constants. In the presence of intractable normalizing constants in the likelihood function, traditional MCMC methods cannot be applied. We propose an approach to sample...

On computational tools for Bayesian data analysis
Robert, Christian P.; Marin, Jean-Michel - Université Paris-Dauphine (Paris IX) - 2010
While Robert and Rousseau (2010) addressed the foundational aspects of Bayesian analysis, the current chapter details its practical aspects through a review of the computational methods available for approximating Bayesian procedures. Recent innovations like Monte Carlo Markov chain, sequential...

Estimation bayésienne approximative par échantillonnage préférentiel
Guillin, Arnaud; Marin, Jean-Michel; Robert, Christian P. - Université Paris-Dauphine (Paris IX) - 2005
For numerous models, it is impossible to conduct an exact Bayesian inference. There are many cases where the derivation of the posterior distribution leads to intractable calculations (due to the fact that this generally involves intractable integrations). The Bayesian computational literature...

Bayesian Core: A practical approach to computational Bayesian statistics
Marin, Jean-Michel; Robert, Christian P. - Université Paris-Dauphine (Paris IX) - 2007
This Bayesian modeling book is intended for practitioners and applied statisticians looking for a self-contained entry to computational Bayesian statistics. Focusing on standard statistical models and backed up by discussed real datasets available from the book website, it provides an...
