I apologise for the low frequency of updates to this blog. The big news is that I am moving back to the UK next month after 23 years in France working for the World Health Organization. I am very excited to be starting a new job in the Department of Statistics at the University of Warwick.
The 2018 edition of the long-running Statistical Practice in Epidemiology using R (SPE) course will take place in Lyon, Fance on 20-24 June 2018 at the International Agency for Research on Cancer. The deadline for applications is 1 April.
If you want to spread the word in our department, please print off the A4 flyer.
The source tarball for JAGS 4.3.0 is now available from Sourceforge. Binary distributions will be available later. See the updated manual for details of the features in the new version. This version is fully compatible with the current version of rjags on CRAN.
There is an opportunity at IARC for a postdoctoral statistician to work on a challenging problem with a big impact.
I have spent the last couple of months updating the JAGS manual for the release of 4.3.0. I have uploaded the manual to Sourceforge so you can now download it. This is mainly for the benefit of people coming to my JAGS tutorial next week at useR! 2017.
This was the final task before releasing JAGS 4.3.0 so you can expect some news on that front fairly soon.

We are pleased to announce the 1st Italian Astrostatistics School that will be held at INAF-Osservatorio Astronomico di Brera, Milano from 12 to 16 June 2017.
The primary goal of the school is to train astronomers to the use of modern statistical techniques, specifically parameter estimation and model selection. The INTENSIVE course, lectured by Stefano Andreon and Roberto Trotta, is characterized by extended laboratory sessions (i.e. individual work at the computer), taking about two thirds of the school attendance. The capacity is limited to 35 participants (first come first served
basis). The school is open to PhD students in astronomy, who have priority (they should register by May 15th), and if space allows, to post-docs and researchers. From May 15th, registration is open to all (subject to availability). Attendance to the course has pre-requirements. For school program, details, and registration see:

Bayescomp 2018 will be held in Barcelona, Spain, on 26-29 March. This is the successor to the MCMski conference series.
Bayes Comp 2018 is a biannual conference sponsored by the ISBA section of the same name. The conference and the section both aim to promote original research into computational methods for inference and decision making and to encourage the use of frontier computational tools among practitioners, the development of adapted software, languages, platforms, and dedicated machines, and to translate and disseminate methods developed in other disciplines among statisticians.
See the conference web site for more details. Note that I am not involved in the organisation of the conference, I am just disseminating the information.
I am giving a pre-conference tutorial on JAGS at useR! 2017 in Brussels on 4 July. You can see the outline of the tutorial on the conference website along with the other tutorials being given the same day.
This is my first pre-conference tutorial. Last year I gave a three day course on JAGS at the University of Zurich, so I have plenty material. My main problem is not over-filling the 3-hour time slot.
On Wednesday, Mathias Drton and I will be presenting a read paper on Bayesian model choice for singular models at the Royal Statistical Society in London. You can read more about it on the RSS web site , where you can also download a preprint. The paper is scheduled to appear, with the discussion, in Series B of the Journal of the Royal Statistical Society next year.
The CRAN package sBIC by Luca Weihs implements the ideas in the paper and includes a series of vignettes that allow you to step through some of the examples in the paper.
… but sometimes you just need a good example to show you how. Saana Isojunno from the University of Saint Andrews wrote to me with an example that stopped working when she upgraded from JAGS 3.4.0 to JAGS 4.2.0. Saana’s model showed the classic signs of a memory leak. Compilation was very slow and memory consumption increased until all available RAM was used and the process was killed by the operating system. Continue reading
