No-op: The case of Case and Deaton

In responding to some recent blog comments I noticed an overlap among our two most recent posts: 1. Mortality rate trends by age, ethnicity, sex, and state 2. When does research have active opposition? The first post was all about the...Show More Summary

When does research have active opposition?

A reporter was asking me the other day about the Brian Wansink “pizzagate” scandal. The whole thing is embarrassing for journalists and bloggers who’ve been reporting on this guy’s claims entirely uncritically for years. See here, for example. Show More Summary

Fighting malaria through metabolism

(Ecole Polytechnique Fédérale de Lausanne) EPFL scientists have fully modeled the metabolism of the deadliest malaria parasite. The model offers unprecedented tools for developing a new generation of antimalarial therapies to overcome drug resistance.

Fighting malaria through mathematical analysis of parasite's metabolism

(PLOS) A new mathematical model, based on the deadliest malaria parasite, Plasmodium falciparum, could help develop antimalarials by identifying key metabolic targets, according to a study published in PLOS Computational Biology by Vassily Hatzimanikatis at École Polytechnique Fédérale de Lausanne (EPFL), Switzerland, and colleagues.

Mortality rate trends by age, ethnicity, sex, and state

There continues to be a lot of discussion on the purported increase in mortality rates among middle-aged white people in America. Actually an increase among women and not much change among men but you don’t hear so much about this as...Show More Summary

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 […]

This could be a big deal: the overuse of psychotropic medications for advanced Alzheimer’s patients

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

Some natural solutions to the p-value communication problem—and why they won’t work

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.

New Twist on Sofa Problem That Stumped Mathematicians and Furniture Movers

(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?

Clarke’s Law: Any sufficiently crappy research is indistinguishable from fraud (Pizzagate edition)

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

Using virtual reality to catch a real ball

(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.

Whassup, Pace investigators? You’re still hiding your data. C’mon dudes, loosen up. We’re getting chronic fatigue waiting for you already!

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

Noise and bias

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

“A blog post that can help an industry”

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
