A theorem saying what's so special about the p-norms.
Just a short post to note that Norwegian Academy of Science and Letters has just announced that the 2017 Abel prize has been awarded to Yves Meyer, “for his pivotal role in the development of the mathematical theory of wavelets”. The actual prize ceremony will be at Oslo in May. I am actually in Oslo […]
I received the following email, entitled “A research lead (potentially bigger than the opioid epidemic,” from someone who wishes to remain anonymous: My research lead is related to the use of psychotropic medications in Alzheimer’s patients. Show More Summary
Blake McShane and David Gal recently wrote two articles (“Blinding us to the obvious? The effect of statistical training on the evaluation of evidence” and “Statistical significance and the dichotomization of evidence”) on the misunderstandings of p-values that are common even among supposed experts in statistics and applied social research.

(University of California - Davis) With some help from 3-D printing, a UC Davis mathematician is trying to crack a problem that frustrates both mathematicians and furniture movers: What's the largest sofa you can fit round a corner?
This recent Pizzagate post by Nick Brown reminds me of our discussion of Clarke’s Law last year. P.S. I watched a couple more episodes of Game of Thrones on the plane the other day. It was pretty good! And so I continue to think this...Show More Summary
(Disney Research) Disney Research scientists have found innovative ways to enhance virtual experiences involving interactions with physical objects by showing how a person using a virtual reality system can use it to reliably catch a real ball.
James Coyne writes: For those of you who have not heard of the struggle for release of the data from the publicly funded PACE trial of adaptive pacing therapy, cognitive behaviour therapy, graded exercise therapy, and specialist medical...Show More Summary
Someone asked me about the distinction between bias and noise and I sent him some links. Then I thought this might interest some of you too, so here it is: Here’s a recent paper on election polling where we try to be explicit about what...Show More Summary
Tim Bock writes: I understood how to address weights in statistical tests by reading Lu and Gelman (2003). Thanks. You may be disappointed to know that this knowledge allowed me to write software, which has been used to compute many billions of p-values. Show More Summary
Eric Loken writes: I guess they needed to add some drama to Hermine’s progress. [background here] P.S. The above post was pretty short. I guess I should give you some more material. So here’s this, from Alex Frankel: I [Frankel] am kind...Show More Summary

Ensemble methods By ensemble methods, I (Bob, not Andrew) mean approaches that scatter points in space and then make moves by inteprolating or extrapolating among subsets of them. Two prominent examples are described in these papers:...Show More Summary
It goes like this. Null-hypothesis-significance-testing (NHST) only works when you have enough accuracy that you can confidently reject the null hypothesis. You get this accuracy from a large sample of measurements with low bias and low variance. Show More Summary
