“C’est un acte belliqueux, c’est sûr. Un acte d’ingérence, c’est clair. Mais ce qui est surtout problématique, c’est qu’il est fait sans attendre l’ouverture de l’enquête internationale. Les faits sont affreux, il faut donc trouver les coupables. Mais encore faut-il qu’une commission internationale puisse mener une enquête indépendante pour pouvoir donner des éléments. Là, il n’y a aucun élément”  8 avril 2017

“La France n’est pas responsable du Vel’ d’Hiv. Je pense que de manière générale, plus généralement d’ailleurs, s’il y a des responsables, c’est ceux qui étaient au pouvoir à l’époque, c’est pas la France.” 9 avril 2017

CosmoPMC released

Martin Kilbinger, an astronomer (cosmologist) with whom we had worked on population Monte Carlo for cosmological inference [during the ANR-05-BLAN-0283- 04 ANR ECOSSTAT grant], has made the PMC C codes available on the CosmoPMC webpage. He has also written a CosmoPMC manual that is now available from arXiv. And he very kindly associated me to this publication, even though I never directly contributed to the codes… On a wider perspective, this collaboration between cosmologists and Bayesian and computational statisticians was both fruitful and enjoyable and I hope we can pursue it in the future. A very nice thing about astronomers (among many!) is that they naturally adopt a Bayesian way of thinking about their parameters. This, plus their high math and programming skills, makes the cost of entering a collaboration very low!
