Just head from Sonia and Judith that our friend and fellow Bayesian Jayanta K Ghosh (জয়ন্ত কুমার ঘোষ in Bengali) has passed away a few days ago in Lafayette. He was a wonderful man, very kind to everyone and open for discussing all aspects of Bayesian theory and methodology. While he worked on many branches of statistics, he is more know to Bayesians for his contributions to Bayesian asymptotics. From Bernstein-von-Mises convergence theorems to frequentist validation of non-informative priors, to the Bayesian analysis of infinite dimensional problems, including consistency of posteriors and rates of convergence, and to Bayesian and Empirical Bayes model selection rules in high dimensional problems. He also wrote an introductory textbook on Bayesian Statistics ten years ago with Mohan Delampady and Tapas Samanta. And a monograph of higher order asymptotics. I knew from this summer that J K was quite sick and am quite sad to learn of his demise. He will be missed by all for his gentleness and by Bayesians for his contributions to the fields of objective and non-parametric Bayesian statistics…

O’Bayes17, next December in Austin

Posted in pictures, Statistics, Travel, University life with tags , , , , , , , , , , , on April 5, 2017 by xi'an

The next edition of the OBayes meetings is taking place this December in Austin, Texas! On the campus of the University of Texas (UT), organised by Carlos Carvalho, Peter Mueller,  James Scott, and Tom Shively. On December 10-13. Following a tradition of more than 20 years—I went to most meetings although I missed the very first conference in West Lafayette, Indiana, and only stayed 27 hours in Shanghai!, plus adopted the O’Bayes logo for the Aussois meeting, even though I meant the number of the year rather than for the edition!!—, this meeting brings together researchers interested in objective Bayes theory, methodology, and applications, and related topics, to provide opportunities for young researchers, and to establish new collaborations and partnerships. (The meeting is the biennial meeting of the Objective Bayes section of the International Society for Bayesian Analysis, of which I happen to be the current president.)

The list of speakers and discussants this year is quite impressive and far reaching, and everyone is more than welcome to present a poster at the workshop. The first (Sun)day will see a series of tutorials, given by members of the scientific committee (myself included), followed by three days of invited talks with discussions,  plus a poster session on Monday night. And possibly a desert excursion on Thursday! It should be a great meeting and I most warmly invite all ‘Og’s readers to join us in Texas!

marathon de Toulouse

Congratulations to Jean-Michel Marin, running his very first marathon in Toulouse this morning! I presume this is in part due to my bad influence, just like George Casella started me running road races (with the World famous Happy Hollow 5K in West Lafayette!)…
