During Easter break, a last minute airbnb reservation led us to visit the cathedral of Amiens (in North-East France, near the Battle of the Somme front) with its (42m) soaring ceilings and its immense nave. The central choir is surrounded by an ambulatory with niches of intricate polychrome sculptures of stories of saints that look like 3D-comics. Similar to those Jim and I already spotted in the cathedral of Chartres! In Amiens, there were several of them, including a vivid representation of the life and afterlife of Saint Fermin. (With an exhumation of his body (below) worth the visit by itself: the priest using the spade is so much into it!) As well as a life of John the Baptist, whose head was supposed to have ended up in the cathedral…

Crêt Saint-Michel, Morgiou, Marseille, June 8, 2010Thanks to a very early start from Paris, and despite horrendous traffic jams in Marseilles, I managed to reach CIRM with ten minutes to spare before my course. After my one-hour class, I was suddenly made aware of the (simplistic) idea that the slice sampling uniforms are simply auxiliary, meaning they can be used in many different ways.

I noticed Natesh Pillai just arXived an extension of his earlier Cauchy paper with XL. He proves that the result on the Cauchy distribution of any convex combination of normal ratios still holds when the pair of vectors is distributed from a product of elliptically symmetric functions. Some of Natesh’s remarks reminded me of the 1970 Sankhyã paper by Kelker on spherically symmetric variables. Especially because of Kelker’s characterisation of elliptically symmetric functions as scale mixtures of normals, which makes perfect sense since the scale cancels.

As I skimmed through my slides yesterday, fearing everyone knew about the MCMC basics, I decided to present today the Rao-Blackwellisation slides I gave in Warwick a few months ago.

snapshots of Oxford Statistics

Following the opening of the new Department of Statistics building in Oxford [which somewhat ironically is the former Department of Mathematics!], a professional photographer was commissioned for a photo cover of this move. Which is incidentally fantastic for the cohesion and work quality of the department, when compared with the former configuration in two disconnected buildings on South Parks Road. Not mentioning the vis-à-vis with Eagle and Child.

As the photographer happened to be there the very day I was teaching my Bayesian module for the OxWaSP PhD students, I ended up in some of the photographs (with no clear memory of this photographer, who was most unintrusive). With my Racoon River Brewing Co. tee-shirt I brought back from Des Moines. And was wearing in a very indirect allusion to the US primaries the night before!

Bayesian week in a statistics month at CIRM

Calanque de Morgiou, Marseille, July 7, 2010As posted earlier, this week is a Bayesian week at CIRM, the French mathematical society centre near Marseilles. Where we meet with about 80 researchers and students interested in Bayesian statistics, from all possible sides. (And possibly in climbing in the Calanques and trail running, if not swimming at this time of year…) With Jean-Michel we will be teaching a short course on Bayesian computational methods, namely ABC and MCMC, over the first two days… Here are my slides for the MCMC side:

As should be obvious from the first slides, this is a very introductory course that should only appeal to students with no previous exposure. The remainder of the week will see advanced talks on the state-of-the-art Bayesian computational methods, including some on noisy MCMC and on the mysterious expectation-propagation technique.
