Narrow progressions in the primes

Tamar Ziegler and I have just uploaded to the arXiv our paper “Narrow progressions in the primes“, submitted to the special issue “Analytic Number Theory” in honor of the 60th birthday of Helmut Maier.

Sharks and Snakes

The Swiss stereotypes do not usually suggest a great sense of humor. But since I’ve been in Zürich, I’ve noticed a certain style of quiet understated humor, in particular in advertising. Here’s one ad for the most famous vegetarian restaurant in Zürich (probably the best in the world): Here’s an ad for the Zürich public […]

Why isn’t replication required before publication in top journals?

Study: Illegal U.S. Residents Staying Years Longer

The number of people living in the U.S. illegally last year was steady at 11.3 million, the Pew Research Center reported Wednesday. But with the passing of time, the illegal population now has been in the U.S. much longer than was the case in previous years. In 2013, the typical undocumented resident had been living in the U.S. Show More Summary

I disagree with Alan Turing and Daniel Kahneman regarding the strength of statistical evidence

It’s funny. I’m the statistician, but I’m more skeptical about statistics, compared to these renowned scientists. The quotes Here’s one: “You have no choice but to accept that the major conclusions of these studies are true.” Ahhhh, but we do have a choice! First, the background. Show More Summary

Why the Data on Justifiable Homicide Just Won’t Do

The FBI's Uniform Crime Reporting Program collects data from the more than 18,000 law enforcement agencies to provide statistics about crime and law enforcement in the U.S. But, it isn't required that agencies submit justifiable homicide data to participate in the program, making the largest database of justifiable homicides in the U.S. very incomplete.

Questions about “Too Good to Be True”

Greg Won writes: I manage a team tasked with, among other things, analyzing data on Air Traffic operations to identify factors that may be associated with elevated risk. I think its fair to characterize our work as “data mining” (e.g., using rule induction, Bayesian, and statistical methods). Show More Summary

Longest Increasing Subsequence

A sequence is a list of integers (or any other ordered type, but we’ll use integers to keep things simple). A subsequence is any, possibly non-consecutive, list drawn from the parent sequence with items in the same order as the parent sequence. An increasing subsequence is a subsequence with all the items in increasing order. […]

Bad Statistics: Ignore or Call Out?

Evelyn Lamb adds to the conversation that Jeff Leek and I had a few months ago. It’s a topic that’s worth returning to, in light of our continuing discussions regarding the crisis of criticism in science. The post Bad Statistics: Ignore or Call Out? appeared first on Statistical Modeling, Causal Inference, and Social Science.
