Tenure track faculty opening at the Center for the Promotion of Research Involving Innovative Statistical Methodology, with Jennifer Hill, Marc Scott, and other world-class researchers. It looks like a great opportunity. The post That’s crazy talk! appeared first on Statistical Modeling, Causal Inference, and Social Science.
Mark Palko is irritated by the Times’s refusal to retract a recounting of a hoax regarding Dickens and Dostoevsky. All I can say is, the Times refuses to retract mistakes of fact that are far more current than that! See here for twoShow More Summary
For each natural number, let denote the quantity where denotes the prime. In other words, is the least quantity such that there are infinitely many intervals of length that contain or more primes. Thus, for instance, the twin prime conjecture is equivalent to the assertion that, and the prime tuples conjecture would imply […]
After reading Rachel and Cathy’s book, I wrote that “Statistics is the least important part of data science... I think it would be fair to consider statistics as a subset of data science.... it’s not the most important part of data science,...Show More Summary

Today’s exercise is my reminder to myself to do a better job of testing. I was porting some prime-number code to Python, one of several preliminary steps to writing a new essay. I am comfortable enough with Python (mostly), and there is nothing particularly tricky about the code, so I wrote the code, tested it […]
A colleague writes: Personally my Kasparov number is two: I beat in a regular tournament game, and beat Kasparov! That’s pretty impressive, especially given that I didn’t know this guy played chess at all! Anyway, this got me thinking, what’s my Kasparov number? OK, that’s easy. Show More Summary
To me, the thing that makes probability fun is that the results are frequently surprising. We've got very strong instincts about how we expect numbers to work. But when you do anything that involves a lot of computations with big numbers, our intuition goes out the window - nothing works the way we expect it […]
Elaine Landry is editing a book called Categories for the Working Philosopher.
It’s time to (somewhat belatedly) roll over the previous thread on writing the first paper from the Polymath8 project, as this thread is overflowing with comments. We are getting near the end of writing this large (173 pages!) paper, establishing a bound of 4,680 on the gap between primes, with only a few sections left […]
In response to some big new push for testing schoolchildren, Mark Palko writes: The announcement of a new curriculum is invariably followed by a round of hearty round of self congratulations and talk of “keeping standards high” as if adding a slide to a PowerPoint automatically made students better informed.

The classical foundations of probability theory (discussed for instance in this previous blog post) is founded on the notion of a probability space – a space (the sample space) equipped with a -algebra (the event space), together with a countably additive probability measure that assigns a real number in the interval to each event. One […]
Objects of the class “Foghorn Leghorn”: parodies that are more famous than the original. (“It would be as if everybody were familiar with Duchamp’s Mona-Lisa-with-a-moustache while never having heard of Leonardo’s version.”) ObjectsShow More Summary
China's relaxation of its one-child policy won't affect the labor supply for decades. Demographers are split on what other effects it will have.
The answer is no, as explained in this classic article by Warren Browner and Thomas Newman from 1987. If I were to rewrite this article today, I would frame things slightly differently—referring to Type S and Type M errors rather than...Show More Summary
I was recently reading yet another botched explanation of Heisenberg's uncertainty principle, and it ticked me off. It wasn't a particularly interesting one, so I'm not going disassemble it in detail. What it did was the usual crackpot quantum dance: Heisenberg said that quantum means observers affect the universe, therefore our thoughts can control the […]
We have today an interview question from Twitter: Consider the following picture: In this picture we have walls of different heights. This picture is represented by an array of integers, where the value at each index is the height of the wall. The picture above is represented with an array as [2,5,1,2,3,4,7,7,6]. Now imagine it […]
Here. And here‘s the backstory. The post BDA class 4 G+ hangout on air is on air appeared first on Statistical Modeling, Causal Inference, and Social Science.
[tl;dr] Producing a piece of research for publication has many stages, and each stage has different needs, requiring different ways of operating. Learning these stages is a key developmental step for a graduate student. In what follows,...Show More Summary
Tomorrow (Thurs) 8h30 (Paris time) I will be teaching my Bayesian Data Analysis class (class4a.pdf and class4b.pdf, you can follow the slides here). We had problems earlier with the regular G+ hangout, so this time we’re trying the G+ On-Air Hangout which I think should work better. Show More Summary
