Posted in Kids, pictures, Statistics, University life with tags conditional probability, cross validated, fiducial inference, it's greek to me, σ-algebra, random variates, students on October 25, 2017 by xi'an**A** revealing [and interesting] question on X validated about ε’s… The question was about the apparent contradiction in writing Normal random variates as the sum of their mean and of a random noise ε in the context of the bivariate Normal variate (x,y), since using the marginal x conditional decomposition led to two different sets of ε’s. Which did not seem to agree. I replied about these ε’s having to live in different σ-algebras, but this reminded me of some paradoxes found in fiducial analysis through this incautious manipulation of ε’s…

## career advices by Cédric Villani

Le Monde has launched a series of tribunes proposing career advices from 35 personalities, among whom this week (Jan. 4, 2017) Cédric Villani. His suggestion for younger generations is to invest in artificial intelligence and machine learning. While acknowledging this still is a research topic, then switching to robotics [although this is mostly a separate. The most powerful advice in this interview is to start with a specialisation when aiming at a large spectrum of professional opportunities, gaining the opening from exchanges with people and places. And cultures. Concluding with a federalist statement I fully share.

## teaching Bayesian statistics in HoChiMin City

Posted in Books, Kids, Statistics, Travel, University life with tags crash course, pho, Saigon, students, The Bayesian Choice, Vietnam on June 5, 2013 by xi'an**T**oday, I gave my course at the University of Sciences (Truòng Dai hoc) here in Saigon in front of 40 students. It was a bit of a crash course and I covered between four and five chapters of The Bayesian Choice in about six hours. This was exhausting both for them and for me, but I managed to keep writing on the blackboard till the end and they bravely managed to keep their focus till the end as well. Since the students were of various backgrounds different from maths and stats (even though some were completing PhD’s involving Bayesian tools) I do wonder how much they sifted from this crash course, apart from my oft repeated messages that everyone had to pick a prior rather than go fishing for *the* prior… *(No pho tday but a spicy beef stew and banh xeo local pancakes!)* Here are the slides for the students:
