Thanks to Matt Denwood, we now have a binary distribution of JAGS 3.4.0 for Mac OS X Mavericks. There is a separate binary for older Mac OS X releases (Snow Leopard, Lion, Mountain Lion). Both binary packages can be downloaded from the files page.
[Update 2014-09-11] The rjags package for Mavericks is now available from CRAN. To make it work, you need to have the right combination of R and JAGS:
- If you installed the R-3.1.1-mavericks.pkg version of R then you need to install JAGS-Mavericks-3.4.0.dmg
- If you installed the R-3.1.1-snowleopard.pkg version of R then you need to install JAGS-SnowLeopard-3.4.0.dmg
If you get an error about a missing symbol then you have the wrong combination of R and JAGS.
If you are still having problems, come to the JAGS forums.
This will be somewhat shorter summary of the second day of DSC 2014. There was a wider variety of presentations today, but I am only going to discuss those that touched on the main theme of the day, which was reproducibility. Continue reading
Peter Dalgaard, Deepayan Sarkar and Martin Maechler in Brixen
This is a report of the first day of the Directions in Statistical Computing (DSC) conference that took place in Brixen, Italy (See here for an introduction). Performance enhancements were the main theme of the day, covering not just improvements to R itself but alternate language implementations. Continue reading
This is one of three planned posts on the 2014 Directions in Statistical Computing (DSC) conference held in Brixen, Italy on 26-27 June. This one is just scene setting. Continue reading
David Spiegelhalter, the driving force behind BUGS, has been made a Knight Batchelor in the Queen’s birthday honours.
David is currently the Winton Professor of the Public Understanding of Risk at the University of Cambridge. If you have not seen his video Professor Risk then I heartily recommend that you watch it.
One of the problems of going to a conference called “MCMSki” is that it is hard to persuade people that you are working rather than extending your Christmas break. These pictures will probably not help. Continue reading
I am off to the MCMSki 2014 meeting in Chamonix. I am talking twice. The first talk is in a session on Computational and Methodological Challenges in evidence synthesis and multi-step (modular models). The title is a bit of a mouthful, but I will be talking about cuts. There is a demand for a cut function in JAGS but it is incredibly hard to implement it properly. In fact the cut function, as currently implemented in OpenBUGS does not work correctly. I have been saying this for years, without making any real progress or providing a solution in JAGS. I agreed to give the talk in order to explain myself to an expert audience.
The second talk is in a round-table discussion on Recent Developments in Software for MCMC with other software developers Andrew Thomas (BUGS), Bob Carpenter (Stan) and Adrien Todeschini (BiiPS). BiiPS is a fork of JAGS that uses the same front end, but sequential Monte Carlo as a back end instead of MCMC.
I will report back after the meeting. In the mean time, you should be able to find a conference diary by Christian Robert at Xi’an’s Og.
