## Research in pair next summer

April 29, 2010
By

Today I received the very good news that our proposal with Jean-Michel Marin to undertake “research in pair” in CIRM, Luminy, a fortnight next summer was accepted! This research centre in Mathematics is a southern and French version of the renowned German centre of Oberwolfach and, while I would have prefered the cool Black Forest

## Course in San Antonio, Texas

Yesterday, I gave my short (3 hours) introduction to computational Bayesian statistics to a group of 25-30 highly motivated students. I managed to cover “only” the first three chapters, as I included some material on Bayes factor approximation and only barely reached Metropolis-Hastings. Here are the slides, modified from the original Bayesian Core slides: (It

## Introducing R on video

Darren Wraith pointed out to me this site proposing a whole series of videos introducing to R. (Unfortunately in a Windows environment.) This can be handy when facing students with no R background… Filed under: R, Statistics, University life Tagged: course, video

## Welcome, Robin!

Robin Ryder started his new blog with his different solutions to Le Monde puzzle of last Saturday (about the algebraic sum of products…), solutions that are much more elegant than my pedestrian rendering. I particularly like the one based on the Jacobian of a matrix! (Robin is doing a postdoc in Dauphine and CREST—under my

## R exam postprocessing

February 19, 2010

Following my three-fold R exam of last month, I had a depressing afternoon meeting (with other faculty members) some students who had submitted R codes that were suspiciously close to other submitted R codes… In other words, it looked very  likely they had cheated. (A long-term issue with my R course, alas!) During this meeting,

## Congruential generators all are RANDUs!

$Congruential generators all are RANDUs!$

In case you did not read all the slides of Regis Lebrun’s talk on pseudo-random generators I posted yesterday, one result from Marsaglia’s (in a 1968 PNAS paper) exhibited my ignorance during Regis’ Big’ MC seminar on Thursday. Marsaglia indeed showed that all multiplicative congruential generators lie on a series of hyperplanes whose number gets ridiculously

## Big’MC seminar

Two very interesting talks at the Big’ MC seminar on Thursday: – Phylogenetic models and MCMC methods for the reconstruction of language history by Robin Ryder – Uniform and non-uniform random generators by Régis Lebrun which are both on topics close to my interest, evolution of languages (I’ll be a philologist in another life!) and uniform random generators. Filed

## Looking for a Bayésien PhD

I just got this email (yes, in French) looking for a Bayesian ready to work on algorithms: Dans le cadre de la société Vekia, nous recherchons un Docteur en statistiques bayésiennes pour un poste sur Lille à pourvoir dès que possible. Vekia est  un éditeur de logiciel pour le commerce fondée en 2007 par deux chercheurs (Pierre-Arnaud

## Bayesian courses in København

I received this announcement about two incoming courses given in København by Andrew Lawson: 1) “*An Introduction to Bayesian Disease Mapping*” A Two-Day Course, April 12.- 13. 2010, University of Southern Denmark This course is designed to provide an introduction to the area of Bayesian disease mapping in applications to Public Health and Epidemiology: 2) “*Advanced Bayesian Disease Mapping*” A

## Typos in Chapters 6-7

January 14, 2010
By

Over the weekend and during the R exams, I managed to complete the solution set for Chapters 6 and 7 of “Introducing Monte Carlo Methods with R”. Chapter 6 only exhibited a few typos, despite me covering most exercises in Chapter 6, hence the merging of both chapters. – in Exercise 6.13, both and
