aftermaths of retiring significance

Beyond mentions in the general press of the retire significance paper, as in Retraction Watch, Bloomberg, The Guardian, Vox, and NPR, not to mention the large number of comments on Andrew’s blog, and Deborah Mayo’s tribune on a ban on free speech (!), Nature of “the week after” contained three letters from Ioannidis, calling for […]

deep and embarrassingly parallel MCMC

Diego Mesquita, Paul Blomstedt, and Samuel Kaski (from Helsinki, like the above picture) just arXived a paper on embarrassingly parallel MCMC. Following a series of papers discussed on this ‘og in the past. They use a deep learning approach of Dinh et al. (2017) to the computation of the probability density of a convoluted and […]

Bayesian econometrics in St. Andrews

A call I received for the incoming 2019 edition of the European Seminar on Bayesian Econometrics (ESOBE), sponsored by the EFaB section of ISBA, which is going to be held at the University of St Andrews in Scotland on Monday 2 and Tuesday 3 September, 2019. I have attended an earlier edition in Venezia and […]

the joy of stats [book review]

David Spiegelhalter‘s latest book, The Art of Statistics: How to Learn from Data, has made it to Nature Book Review main entry this week. Under the title “the joy of stats”,  written by Evelyn Lamb, a freelance math and science writer from Salt Lake City, Utah. (I noticed that the book made it to Amazon […]

Отцы и дети [Fathers and Children]

Following a mention made of this book on the French National Public radio, I read Turgenev’s Fathers and Sons for the first time last month. This is a fabulous novel, reflecting about the failed modernisation of Russia after the abolishing of serfdom and the rise of nihilism in the younger generation. Having re-read Dostoievski’s Demons […]

numbers of numbers with numbers of their numbers

A funny riddle from The Riddler where the number of numbers that indicate the numbers of their numbers is requested. By which one means numbers like 22 (two 2’s) and 21322314 (two 1’s, three 2’s, two 3’s and one 4), the convention being that “numbers consist of alternating tallies and numerals”. And that numerals are […]

Bayes on the Beach

This year, the now traditional Bayes on the Beach conference will take place in Surfers Paradise (Gold Coast, Queensland, Australia) on 25th – 27th November.

BayesComp 20 [registration open]

The registration page is now open for BayesComp 20, in Gainesville, Florida, next 7-10 Jan 2020. The fees are quite moderate, imho, given the fact that they cover all breaks (if not the conference dinner). Deadline for these early rates is August 14. There will also be travel support from various sponsors, with deadline for […]

Ph.D. scholarships at ENSAE ParisTech‐CREST

ENSAE ParisTech and CREST are currently inviting applications for 3-year PhD scholarships in statistics (and economics, finance, and sociology). There is no constraint of nationality or curriculum, but the supervisor must be from ENSAE (Paris-Saclay) or ENSAI (Rennes-Bruz).  The deadline is May 1, to be sent to Mrs Fanda Traore, at ensae.fr. Applications should submitted […]

ERC panel [step #2]

Another post that was written ages ago, about the second round of the European Research Council (ERC) panel on starting grants for mathematics in which I took part as an expert and not as an applicant. While anonymity possibly fell apart for the several dozens of applicants who were shortlisted for interview, in particular more […]

Metropolis gets off the ground

An X validated discussion that toed-and-froed about an incomprehension of the Metropolis-Hastings algorithm. Which started with a blame of George Casella‘s and Roger Berger’s Statistical Inference (p.254), when the real issue was the inquisitor having difficulties with the notation V ~ f(v), or the notion of random variable [generation], mistaking identically distributed with identical. Even […]

the Frankenstein chronicles

Over a lazy weekend, I watched the TV series The Frankenstein Chronicles, which I found quite remarkable (if definitely Gothic and possibly too gory for some!). Connections with celebrities of (roughly) the time abound: While Mary Shelley makes an appearance in the first season of the series, not only as the writer of the famous […]

no country for old liars

A puzzle from the Riddler about a group of five persons, A,..,E, where all and only people strictly older than L are liars, all making statements about others’ ages: A: B>20 and D>16 B: C>18 and E<20 C: D<22 and A=19 D: E≠20 and B=20 E: A>21 and C<18 The Riddler is asking for the […]
