Beta translation done!

Beta translation done!

Once my team of four translators had handed back to me all the chapters of the French version of Introducing Monte Carlo Methods with R to me, I had to go over the book to ensure some minimal consistency between the chapters. I started the editing in the plane to Vancouver but did not get

Julian Besag 1945-2010

I have just learned that Julian Besag passed away last morning in Bristol after being admitted to the hospital two weeks ago. He was a leading figure of our field, a fiercely independent thinker, a brilliant statistician, and undoubtedly the clearest pretendent to having fathered MCMC. His influence on the field of spatial statistics will

Recent arXiv postings

With too little time, too many things to do on my plate, here are some recent arXiv postings I won’t have time to comment: Adaptive Monte Carlo on multivariate binary sampling spaces. (arXiv:1008.0055v1) Mixture Decomposition of Distributions using a Decomposition of the Sample Space. (arXiv:1008.0204v1) Bayesian Model Selection for Beta Autoregressive Processes. (arXiv:1008.0121v1) Reference priors

JSM 2010 [day 3]

The same pattern as yesterday occurred, namely that the sessions that most interested me were all together at the 10:30 and 2pm slots, while there was no talk (besides the official ones) after 4pm… After another run around Stanley Park, I took the opportunity of being late for the first session to sit outside and

JSM 2010 [day 2]

After a very good early run in Stanley Park, I went to a morning session on new statistical challenges in genetics, but unfortunately could not keep focussed enough (due to a very short night, still being not tuned to Pacific time!) so I ended up chatting with Sid Chib at the Springer booth about the

JSM 2010 [day 1]

The first day at JSM is always a bit sluggish, as people slowly drip in and get their bearings. Similar to last year in Washington D.C., the meeting takes place in a huge conference centre and thus there is no feeling of overcrowded . It may also be that the peripheric and foreign location

StatProb [wiki]

Via the support of Springer, probability and statistics societies are launching a specialised wiki called StatProb. It operates as a wiki in that authors can submit short articles on any topic, with further co-authors joining in later to improve those articles, but with the contents guaranteed via the filter of an editorial

IMIS & AMIS

A most interesting paper by Adrian Raftery and Le Bao appeared in the Early View section of Biometrics.  It aims at better predictions for HIV prevalence—in the original UNAIDS implementation, a naïve SIR procedure was used, based on the prior as importance function, which sometimes resulted in terrible degeneracy—, but its methodological input is about

A summer of books

The summer started with a research in pair session in CiRM on the R edition of Bayesian Core, but I am also involved two other book projects. The first one was mentioned in a previous post, namely the translation of Introducing Monte Carlo Methods with R into French. I have now recovered all translated chapters,

Asher’s enigma

Asher’s enigma

On his Probability and statistics blog, Matt Asher put a funny question (with my rephrasing): Take a unit square. Now pick two spots at random along the perimeter, uniformly. For each of these two locations, pick another random point from one of the three other sides of the square and draw the segment. What is
