re-read paper

Today, I attended the RSS Annual Conference in Newcastle-upon-Tyne. For one thing, I ran a Memorial session in memory of George Casella, with my (and his) friends Jim Hobert and Elias Moreno as speakers. (The session was well-attended if not overwhelmingly so.) For another thing, the RSS decided to have the DIC Read Paper by David Spiegelhalter, Nicky Best, Brad Carlin and Angelika van der Linde Bayesian measures of model complexity and fit re-Read, and I was asked to re-discuss the 2002 paper. Here are the slides of my discussion, borrowing from the 2006 Bayesian Analysis paper with Gilles Celeux, Florence Forbes, and Mike Titterington where we examined eight different versions of DIC for mixture models. (I refrained from using the title “snow white and the seven DICs” for a slide…) I also borrowed from our recent discussion of Murray Aitkin’s (2009) book. The other discussant was Elias Moreno, who focussed on consistency issues. (More on this and David Spiegelhalter’s defence in a few posts!) This was the first time I was giving a talk on a basketball court (I once gave an exam there!)

  1. Re “snow white…”: you’ve spent too much time with Pierre Jacob ;-)
