futher attacks on reproductive rights

The relentless go at eroding and eventually banning abortion rights in the US has stepped even further with the US Food and Drug Administration (FDA) attempt at banning the European organisation Aid Access from providing abortive pills (Mifepristone and Misoprostol) to US women, based on the argument of “risk to consumers [sic] of unapproved new […]

A precursor of ABC-Gibbs

Following our arXival of ABC-Gibbs, Dennis Prangle pointed out to us a 2016 paper by Athanasios Kousathanas, Christoph Leuenberger, Jonas Helfer, Mathieu Quinodoz, Matthieu Foll, and Daniel Wegmann, Likelihood-Free Inference in High-Dimensional Model, published in Genetics, Vol. 203, 893–904 in June 2016. This paper contains a version of ABC Gibbs where parameters are sequentially simulated […]

assessing MCMC convergence

When MCMC became mainstream in the 1990’s, there was a flurry of proposals to check, assess, and even guarantee convergence to the stationary distribution, as discussed in our MCMC book. Along with Chantal Guihenneuc and Kerrie Mengersen, we also maintained for a while a reviewww webpage categorising theses. Niloy Biswas and Pierre Jacob have recently […]

Tony nominations mean nothing

Someone writes: I searched up *Tony nominations mean nothing* and I found nothing. So I had to write this. There are currently 41 theaters that the Tony awards accept when nominating their choices. If we are being as generous as possible, we could say that every one of those theaters will be hosting a performance […]

Using one RNG to sample another

Suppose you have two pseudorandom bit generators. They’re both fast, but not suitable for cryptographic use. How might you combine them into one generator that is suitable for cryptography? Coppersmith et al [1] had a simple but effective approach which they call the shrinking generator. The idea is to use one bit stream to sample […]

non-uniform Laplace generation

This year, the French Statistical Society (SFDS) Prix Laplace has been granted to Luc Devroye, author of the Non-Uniform Random Generation bible. among many achievements!, prize that he will receive during the 2019 meeting in Nancy, this very week.

Rock, paper, scissors, algebra

Aatish Bhatia posted something interesting on Twitter: if you define multiplication on Rock, Paper, Scissors to be the winner of a match, the result is commutative but not associative. Here’s a neat thing about the algebra of Rock, Paper, Scissors. If you define ‘multiplication’ as the game’s winner, then it’s commutative, i.e. P x R […]

last call for O’Bayes in Warwick

This is a last call for late participants or would-be participants to the O’Bayes conference at the end of the month, in Warwick on 28 June – 02 July, and right after the BNP 12 conference. Posters can still be submitted to me and registrat…
