Here are the [recycled] slides for the introductory lecture I gave this morning at CIRM, with the side information that it appears Slideshare has gone to another of these stages when slides cannot be played on this blog [when using Firefox]…

[On an Air France flight for Birmingham, two young French students apparently studying in Warwick kept blathering the entire time, with an utter lack of concern for their surroundings. Note: Les Marseillais is a particularly idiotic reality show on French TV.]

  • …grave, c’est sûr, moi aussi j’ai arrêté, j’avais trop d’épisodes à rattraper…

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.
