integral priors for binomial regression
Diego Salmerón and Juan Antonio Cano from Murcia, Spain (check the movie linked to the above photograph!), kindly included me in their recent integral prior paper, even though I mainly provided (constructive) criticism. The paper has just been arXived. A few years ago (2008 to be precise), we wrote together an integral prior paper, published in ...

Le Monde puzzle [#827]
Back to R (!) for the current Le Monde puzzle: Given an unknown permutation of the set {1,…,6}, written on the faces of a cube, there exist a sequence of summits such that increasing by one unit the three numbers of the faces sharing the successive summits in the sequence leads to identical values over all faces. What was the initial permutati...

9th IMACS seminar on Monte Carlo Methods, Annecy
As astute ‘Og’s readers may have gathered (!), I am now in Annecy, Savoie, for the 9th IMACS seminar on Monte Carlo Methods. Where I was kindly invited to give a talk on ABC. IMACS stands for “International Association for Mathematics and Computers in Simulation” and the conference gathers themes and sensibilities I am not familiar with. ...

Le Monde puzzle [#825]
The current puzzle is the last one before the summer break and not exciting enough to take along: Take the first ten digits, create five pairs out of those, and for each pair (x,y) derive the quantity (min(x,y)+1.5max(x,y)). What is the collection of pairs that maximises the product of those quantities? I wrote the following R code in the train...

informative hypotheses (book review)
The title of this book Informative Hypotheses somehow put me off from the start: the author, Hebert Hoijtink, seems to distinguish between informative and uninformative (deformative? disinformative?) hypotheses. Namely, something like H0: μ1=μ2=μ3=μ4 is “very informative” and the alternative Ha is completely uninformative, while the “al...

Le Monde puzzle [#835]
The current puzzle is apparently suffering from combinatoric complexity : N persons (with 20≤N≤23) are sitting around a round table and everyone has a green or red token. Both colours are represented. First, each player with a red token take the token of the player immediately to her or his left. Second, each player with at least one green t...
