a most unexpected citaXion!

In a conversation between (Canadian) Christian Genest (whom I first met in 1986, in a dinner cruise of Lac Léman organised by the French Statistical Society for its national meeting in Lausanne) and David Bellhouse that recently appeared in the International Statistical Review of January 2025 figures the following bit that quotes my… review of Bellhouse’s  William Playfair!

Christian Genest: More recently, you produced some very original work on William Playfair (Bellhouse, 2023), who is generally regarded as the founder of graphical methods in statistics. What about it?

David Bellhouse: The best I can do here is to quote from Christian Robert’s review of my book in Chance (Robert, 2024).

‘The impressions I kept from reading this detailed account of a perfect unknown (as far as I am concerned) are of a rather unpleasant, unappealing, unsuccessful, fame-seeking, inefficient, short-sighted, self-aggrandizing, bigoted, dishonest character, a ‘rascal’ in Stieglerian terms, running away from his debtors for most of his life, with many jail episodes for bankruptcy, while trying to make a living from all sorts of doomed commercial projects, ill-conceived scams, short-lived blackmailing attempts, and mediocre books that did not sell to many’.

I am glad David enjoyed the quote (to which I may have invested more effort than usual to give it a sort of Dickensian flavour). Incidentally, I learned there that David was a French horn player (which would have been my first choice of musical instrument had I been given a choice when starting playing music!)

a journal of the chaos, conquest, war, fried meals, and death year

Read Charles de Lint’s Jack, The Giant-Killer, which is just as terrible as it sounds!  The only redeeming feature is that it takes place in Ottawa, Canada, where the author lives, as I could relate to the places of down-town Ottawa mentioned therein. Otherwise, a terrible book inspired from classical folk tales, with an unpleasant undertone about homeless people… Can’t see at all why this book was recommended in one of Tor’s tribunes on forgotten classics or something like that.

Cooked a variety of spicy stir-fries while staying at a Warwick maths house with Josh and Stan two weeks ago, Josh adding the sweet-potato pancakes, which made the mini-nans somewhat superfluous. The common colour theme came from abusing the curry dispenser. Also had a great Greek mezze dinner in Pointe Rouge, Marseille, to celebrate the Marseille-Cassis race. (The place was a wee bit too popular, though, patronised the same evening by some actors of the local soap opera, as well as a group that sounded like a hen-party.)

Watched the first ½ hour of Shirkers, a pseudo-documentary about a movie made twenty years earlier by three young women in Singapore. Very original, especially for the delve into the 1990’s Singapore pop culture. And the fanzines that reminded me of my teenage years. No wonder it won the Sundance Film Festival  documentary award. Also tried Season 2 of Hellbound, but could not find the slightest excitement to even complete the first episode…

a journal of the chaos, conquest, guerre, famine, and death year

Read Guerre (War) by Louis-Ferdinand Céline (with a cover by Tardi, as for the other books of his in the Folio collection), a recent recovery of a 1934 manuscript that had been stolen from his Paris apartment in 1944 when he fled to Sigamaringen along with the collaborationist Pétain government. As described (with much whining and cynicism) in D’un château l’Autre (Castle to Castle). If Voyage au Bout de la Nuit is to be considered as one of the strongest anti-war novels ever, Guerre sounds like the original, uncensored , unedited—a few words and the earlier pages are missing—, version of this book, despite being written later. A short but intense 150 pages raw fall into the mindset of a surviving WWI soldier that feels like treading a sewer but offers an in-your-face testimony on the unlimited amorality of war and men, with no heroes… As mentioned earlier, I also read Han Kang’s The Vegetarian, which is another kind of shell-shocking journey in three mindsets around the central figure of the sister fasting herself to death, whose perspective is barely heard. Raw, again, with introspection and returns to childhood trauma, impressive in many respects and so original!

Made jars and jars of green tomato jam as the tomato plants had started to rot due to the enormous volume of rain we got in September and October. Also made a pie with chestnuts and chocolate and the very last raspberries, after my attempt at chestnut butter did not prove successful. With a sprinkle of matcha to substitute for sugar. (Figs are also almost done for the season, after a massive harvest that I mostly shared with my Dauphine colleagues.)

à la journée François Perron

Wonderful day celebrating my long-term friend François Perron’s career, at the Université de Montréal! In full autumnal glory! With several long-time-no-see friends attending and presenting their work and connecting with François’ achievements, incl. Éric Marchand on Stein prediction for spherically symmetric distributions, where the predicted vector y appears in the same quadratic form as the observed one x, with the same location parameter, a setting that turns prediction into estimation of that parameter, a 2019 paper with Dominique Fourdrinier and Bill Strawderman,A
Mylène Bédard on a generalised optimal scaling of annealed MALA, with higher speeds in transient cases than known so far,t. Yves Atchadé on cyclical MCMC, a rejection free version of Radford Neal’s parallel tempering, that sometimes fails to converge
and Alex Bouchard-Côté on escaping the curse of dimensionality by interpolations of the target, which is a variant of simulated tempering (quite the theme of the day!), and happened to be his invited lecture for the 2024 CRM-SSC prize, awarded right after. Unfortunately I had to catch my plane and face the notorious jams to the airport. (And, fortunately, I had attended Saifuddin Syed’s related talk at Mostly MC the week before!)
