The full and definitive program of the O’Bayes 2019 conference in Warwick is now on line. Including discussants for all papers. And the three [and free] tutorials on Friday afternoon, 28 June, on model selection (M. Barbieri), MCMC recent advances (G.O. Roberts) and BART (E.I. George). Registration remains open at the reduced rate and submissions of posters can still be sent to me for all conference participants.

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 #1 bestseller, albeit in the Craps category!, which I am unsure is completely adequate!, especially since the book is not yet for sale on the US branch of Amazon!, and further Amazon #1 in the Probability and Statistics category in the UK.) I have not read the book yet and here are a few excerpts from the review, quoted verbatim:

“The book is part of a trend in statistics education towards emphasizing conceptual understanding rather than computational fluency. Statistics software can now perform a battery of tests and crunch any measure from large data sets in the blink of an eye. Thus, being able to compute the standard deviation of a sample the long way is seen as less essential than understanding how to design and interpret scientific studies with a rigorous eye.”

“…a main takeaway from the book is a sense of circumspection about our confidence in what is known. As Spiegelhalter writes, the point of statistical science is to ease us through the stages of extrapolation from a controlled study to an understanding of the real world, `and finally, with due humility, be able to say what we can and cannot learn from data’. That humility can be lacking when statistics are used in debates about contentious issues such as the costs and benefits of cancer screening.

Trip to Montpellier & StatLearn10

Posted in Statistics, Travel, University life with tags , , , , on January 28, 2010 by xi'an

Today, I went to Montpellier for a meeting of our EMILE ANR team, but when I got to the airport at 6:30 this morning, the fuel providers went on an impromptu strike, which lasted for about one hour! I cannot see the point of such mini-strikes… Anyway, I managed to eventually reach Montpellier and we had a good working session around the ABC paper entitled “An Adaptive Sequential Monte Carlo Method for Approximate Bayesian Computation” by Pierre Del Moral, Arnaud Doucet and Ajay Jasra and discussed in that earlier post and available on-line, if not on arXiv.

Jean-Michel Marin also mentioned to me a workshop taking place in Paris in the next couple of days, called StatLearn10 and focussing on Challenging problems in Statistical Learning (organised by Charles Bouveron and Gilles Celeux). Given that my agenda is already full for those days, I am going to miss the workshop but it sure looked interesting!
