state of the art in sampling & clustering [workshop]

Posted in Books, pictures, Statistics, Travel, University life with tags , , , , , , , , , , on September 17, 2020 by xi'an

Next month, I am taking part in a workshop on sampling & clustering at the Max-Planck-Institut für Physik in Garching, Germany (near München). By giving a three hour introduction to ABC, as I did three years ago in Autrans. Being there and talking with local researchers if the sanitary conditions allow. From my office otherwise. Other speakers include Michael Betancourt on HMC and Johannes Buchner on nested sampling. The remote participation to this MPI workshop is both open and free, but participants must register before 18 September, namely tomorrow.

the story of Gertrud and Auguste Macé

Posted in Uncategorized with tags , , , , , , , , , , , , , , , , on August 6, 2020 by xi'an

The discussions about the links between early statistics and eugenism brought back to memory the tragic story of a German-Norman couple, friends of my grandparents, Gertrud(e) and Auguste Macé, whom I met in the mid 1980’s. Auguste Macé was a school friend of my grandmother, born near the harbour city of Granville, Manche and, like my grandparents,  a war orphan, son of a French conscript killed in combat during WW I. During WW II, when Nazi Germany promptly invaded France in the Spring of 1940, Auguste Macé was part of the millions of French conscripts captured by German troops and sent to a stalag, in North-Eastern Germany (Prussia), where he was made to work in farms missing their workforce conscripted to war. In one of these farms, he met Gertrud, daughter of the farm owners, they fell in love, and Gertrud eventually got pregnant. When her pregnancy was revealed, Auguste was sent to another POW camp. And, while Gertrud was able to give birth to a baby boy, she was dreadfully punished by the Nazis for it: as she had broken their racial purity laws, she was sterilised and prevented from having further children, presumably staying in her parents’ farm. At the end of WW II, Auguste was freed by Soviet troops and went searching for Gertrud. It took him around six months of traveling in the chaotic post-war Germany, but he eventually found both her and their son! They then went back to Auguste’s farm, in Normandy, where they spent the rest of their life, with further hardships like the neighbourhood hostility to a Franco-German couple, lost their young adult son in circumstances I cannot remember, and tragically ending their life together in a car accident in 1988, on a trip to Germany… [When remembering this couple, I have been searching on-line for more information about them but apart from finding the military card of Auguste’s father and Auguste’s 1988 death record by INSEE, I could not spot any link in birth or wedding certificates or in the 98 lists of WW II French POWs. Where I could not find my great-uncle, either.]

additional deaths in England & Wales

David Spiegelhalter wrote another piece for The Guardian about the number of COVID-related deaths in Britain, remarking that with the objective statistic of excess death, the kingdom is doing worse than any other country, including Belgium which is reported as the worst performer in the fight again the pandemic based on its reported COVID death numbers. David also shows the proper degree of caution in providing reasons for this terrible record rather than starting the blame game. One factor differentiating England from other countries like Italy being the spread of its COVID clusters, partly due to the higher mobility of the population, in particular its travelling for vacations. (The comparison also reveals a stable higher level of overall mortality in the UK when compared with south-west EU countries, except Portugal. It surprisingly misses Germany, which is unlikely to be a country with missing statistics!)

Another series I watched during quarantine is the short and powerful Unorthodox, by Anna Winger, featuring the fantastic actress Shira Haas as Etsy, fleeing her unhappy marriage and the stifling rules set by her Hasidic community in Williamsburg, New York, to seek refuge in Berlin, although ambivalent to get help from her distanced mother once there. I found the story quite moving and intense in the slow unfolding of Etsy’s progressive unraveling of her un-orthodoxy and of her desperate escape into a world she knows nothing about. While her difficulties in apprehending this new universe are well rendered, I however find the part of the story when she joins a friendly group of music students somewhat too lazy a plot, although her fight there for achieving autonomy by herself only is remarkably transcribed. I am equally quite impressed by the show immersion into the Hasidic community, which is putting a considerable effort in replacing their tradition into an historical perspective and exposing the outworldly separation between men and women, who are essentially reduced to becoming mothers. The main strength of Unorthodox is that it keeps away from manichaeism, with people stuck into a frozen tradition and not seeing the oppression it induces. As most often with fundamentalism.
