The Ben Geen case: Did a naive interpretation of a cluster of cases send an innocent nurse to prison until 2035?

In a paper called “Rarity of Respiratory Arrest,” Richard Gill writes: Statistical analysis of monthly rates of events in around 20 hospitals and over a period of about 10 years shows that respiratory arrest, though about five times less frequent than cardio-respiratory arrest, is a common occurrence in the Emergency Department of a typical smaller […]

“An Experience with a Registered Replication Project”

Anne Pier Salverda writes: I came across this blog entry, “An Experience with a Registered Replication Project,” and thought that you would find this interesting. It’s written by Simone Schnall, a social psychologist who is the first author of an oft-cited Psych Science(!) paper (“Cleanliness reduces the severity of moral judgments”) that a group of […]

Differences between econometrics and statistics: From varying treatment effects to utilities, economists seem to like models that are fixed in stone, while statisticians tend to be more comfortable with variation

I had an interesting discussion with Peter Dorman (whose work on assessing the value of a life we discussed in this space a few years ago). The conversation started when Peter wrote me about his recent success using hierarchical modeling for risk analysis. He wrote, “Where have they [hierarchical models] been all my life? In […]

Afterward, I received the following question from Fabrizzio Sanchez: As hard as it is to do, I thought it was good to try and define what exactly makes for an ethical violation. Your third point noted that it needed […]

Stan World Cup update

The other day I fit a simple model to estimate team abilities from World Cup outcomes. I fit the model to the signed square roots of the score differentials, using the square root on the theory that when the game is less close, it becomes more variable. 0. Background As you might recall, the estimated […]

Open-source tools for running online field experiments

Dean Eckles points me to this cool new tool for experimentation: I [Eckles] just wanted to share that in a collaboration between Facebook and Stanford, we have a new paper out about running online field experiments. One thing this paper does is describe some of the tools we use to design, deploy, and analyze experiments, […]
