This is the third thread for the Polymath8b project to obtain new bounds for the quantity either for small values of (in particular ) or asymptotically as. The previous thread may be found here. The currently best known bounds on are: (Maynard) Assuming the Elliott-Halberstam conjecture,. (Polymath8b, tentative). Assuming Elliott-Halberstam,. (Polymath8b, […]
Here I’m using the term “liquidate” the economics sense (conversion of an asset into cash) rather than the Rocky-and-Bullwinkle sense of the word. Here’s the story: Katherine Chen writes: An executive summary version of Ackman and Dineen’s...Show More Summary

I’d've given this blog the name, tl;dr. Too late to change it now, though, I think! The post If I could’ve done it all over again appeared first on Statistical Modeling, Causal Inference, and Social Science.
On the sister blog we’re supposed to switch to catchy headlines to match our Big Media presence. I actually think that’s a good idea. It’s not easy to write good titles, and it’s worth trying to do better in that regard. But coming up...Show More Summary
Today’s exercise is our five hundredth! It’s hard to believe. I remember writing the fiftieth exercise and thinking I would never get to a hundred. Even after all this practice it is hard to write two exercises every week, but your comments and private emails and referrals from other web sites sustain me. Many thanks […]
On a standard English keyboard, the letters that a touch-typist strikes with the fingers of the left hand are Q, W, E, R, T on the top row, A, S, D, F, G on the home row, and Z, X, C, V, B on the bottom row. For instance, words like FAST and ZEBRAS are […]

(This is an extended blog post version of my talk “Ultraproducts as a Bridge Between Discrete and Continuous Analysis” that I gave at the Simons institute for the theory of computing at the workshop “Neo-Classical methods in discrete analysis“. Some of the material here is drawn from previous blog posts, notably “Ultraproducts as a bridge […]
Stan is alive and well. We’re up to 523 users on the users list. We’re working on a v2.1.0 release now and we hope to release it in within the next couple of weeks. The post Stan (quietly) passes 512 users appeared first on Statistical Modeling, Causal Inference, and Social Science.
A reader of this blog apparently likes the way I explain things, and wrote to me to ask a question: what is an operating system? And how does a computer know how to load it? I'm going to answer that, but I'm going to do it in a roundabout way. The usual answer is something […]

Paul Kedrosky writes: Curious if you’ve looked at the current debate about Tesla fires, statistically speaking. Lots of arm-waving about true/sample proportions, sample sizes, normal approximations, etc. Would love to see a blog post if it intrigues you at all. Show More Summary
We have a new “Objects of the class,” and it’s a good one! Here’s what happened. I came across a thoughtful discussion by Mark Palko of how it was that Secretary of Education Arne Duncan ticked off so many people with his recent remarks...Show More Summary
Usually I don’t post answers to questions right away, but Mark Liberman was kind enough to answer my question yesterday so I think I should reciprocate.

On the side of less regulation is Alex Tabarrok in “Our DNA, Our Selves”: At the same time that the NSA is secretly and illegally obtaining information about Americans the FDA is making it illegal for Americans to obtain information about themselves. Show More Summary
This exercise is intended for beginning programmers who need to strengthen their understanding of linked lists. It comes in three parts: First, write a function that reverses the elements of a linked list pairwise; for instance, given the list (1 2 3 4 5 6) the pairwise reversal is (2 1 4 3 6 5). […]
