Fate & Fortune [book review]

After enjoying very much the first book, Hue & Cry, in the Hew Cullan series by Shirley McKay, I bought the following ones and read Fate & Fortune over the vacation break. If anything, I enjoyed this one even more, as it disclosed other aspects of 16th Century Scotland, still with the oppressive domination of […]

revisiting marginalisation paradoxes [Bayesian reads #1]

As a reading suggestion for my (last) OxWaSP Bayesian course at Oxford, I included the classic 1973 Marginalisation paradoxes by Phil Dawid, Mervyn Stone [whom I met when visiting UCL in 1992 since he was sharing an office with my friend Costas Goutis], and Jim Zidek. Paper that also appears in my (recent) slides as […]

Le Monde puzzle [#1083]

A Le Monde mathematical puzzle that seems hard to solve without the backup of a computer (and just simple enough to code on a flight to Montpellier): Given the number N=2,019, find a decomposition of N as a sum of non-trivial powers of integers such that (a) the number of integers in the sum is […]

the last argument of drivers

When vaguely listening to the national public radio France Inter last night, while cooking dinner, I heard Patrick Septiers, president of le conseil départemental de Seine et Marne, express his (electorate catering) opposition to the new 80km/h speed limit on national and departmental roads on the most rational (!) argument that delivery trucks drove at […]

the adoration of the golden car

As the demonstrations by the “gilets jaunes” become a fixture of French Saturdays, the French government is gradually giving up on the reforms it had started and is in particular catering to the car [and motorbike] lobby that started the protests. The symbol itself comes from the yellow fluorescent jackets found in every car and […]

Le Monde puzzle [#1081]

A “he said-she said” Le Monde mathematical puzzle (again in the spirit of the famous Singapore high-school birthdate problem): Abigail and Corentin are both given a positive integer, a and b, such that a+b is either 19 or 20. They are asked one after the other and repeatedly if they are sure of the other’s […]

revisiting the Gelman-Rubin diagnostic

Just before Xmas, Dootika Vats (Warwick) and Christina Knudson arXived a paper on a re-evaluation of the ultra-popular 1992 Gelman and Rubin MCMC convergence diagnostic. Which compares within-variance and between-variance on parallel chains started from hopefully dispersed initial values. Or equivalently an under-estimating and an over-estimating estimate of the MCMC average. In this paper, the […]

the future of conferences

The last issue of Nature for 2018 offers a stunning collection of science photographs, ten portraits of people who mattered (for the editorial board of Nature), and a collection of journalists’ entries on scientific conferences. The later point leading to interesting questioning on the future of conferences, some of which relate to earlier entries on […]

and it only gets worse…

““This is absolutely the stupidest thing ever,” said Antar Davis, 23, a former zookeeper who showed up in the elephant house on Friday to take one last look at Maharani, a 9,100-pound Asian elephant, before the zoo closed.” The New York Times, Dec 29, 2018 “The Trump administration has stopped cooperating with UN investigators over […]

Ka [book review]

My last book of the year (2018), which I finished one hour before midnight, on 31 December! Ka is a book about a crow, or rather, a  Crow, Dar Oakley (or, in full, Dar of the Oak by the Lea), told from his viewpoint, and spanning all of Anthropocene, for Dar Oakley is immortal [sort […]

free fall [fake]

As I was looking for the location of a picture serving as a background image for Windows 10 log-in page, I came across several versions of the above, supposedly showing a climber failing to grab another climber’s hand and as a result falling. Or “falling” as the image is obviously doctored, most likely by removing […]

severe testing : beyond Statistics wars?!

A timely start to my reading Deborah Mayo’s [properly printed] Statistical Inference as Severe Testing (How to get beyond the Statistics Wars) on the Armistice Day, as it seems to call for just this, an armistice! And the opportunity of a long flight to Oaxaca in addition… However, this was only the start and it […]
