Cambridge publishes a series of short academic titles called ‘Elements’. There are dozens of them and, for a few weeks only after publication, they can be freely downloaded in pdf format. They vary in quality. Some are very useful. For others, the quality is commensurate with the price you pay....

It’s helpful to think of statistical power as determined by the ratio , where is the treatment effect and SE is the standard error of the estimate.1 1 Bloom (1995) has a really beautiful paper on this idea. It’s one of my favorites. I also have a preprint on the topic.I like this ratio because it...

Power Rules This post is based on this paper called “Power Rules.” We can think of statistical power as determined by the ratio , where is the treatment effect and SE is the standard error of the estimate. To reason about statistical power, one needs to make assumptions or predictions about...

As security researchers, we are often required to think creatively in order to think of edge cases and find vulnerabilities. Creativity is commonly referred to as the attribute of ‘non-systematical’ thinking, ‘non-analytical’ thinking, or in other words - thinking outside the box. So much so that...

In Rainey and McCaskey (2021), Kelly McCaskey and I offer a accessible and practical (re)introduction to Firth’s penalized maximum likelihood estimator that (1) corrects the small sample bias and (2) reduces the excessive variance of the usual maximum likelihood estimator. Below, I bookmark other...

A Paper This post turned out to be somewhat popular, so I’ve written up a more formal, careful description of the idea in a full-length paper. You can find the preprint “Power Rules” here. Background I’ve wrapped up the argument that you should pursue statistical power in your experiments....

Background When I give students formula for confidence intervals, I find that students don’t have a sharp concept of how those confidence intervals work—even if I explain the components of the formula well. Even though they understand—seemingly very well—that the point estimate is noisy, they...

A Paper This post turned out to be somewhat popular, so I’ve written up a more formal, careful description of the idea in a full-length paper. You can find the preprint “Power Rules” here. Background In this post, I address confidence intervals that are nestled right up against zero.1 These...

Fantastic and well-deserved news this morning with the Clark Medal being awarded to Emi Nakamura, who has recently moved from Columbia to Berkeley. Incredibly, Nakamura’s award is the first Clark to go to a macroeconomist in the 21st century. The Great Recession, the massive changes in global...

Reflections on the past ten years of my career: things I've learned. The first lesson was profound: a method to solve any problem.
