A puzzle about the latest test ban (or ‘don’t ask, don’t tell’)

A large number of people have sent me articles on the “test ban” of statistical hypotheses tests and confidence intervals at a journal called Basic and Applied Social Psychology (BASP)[i]. Enough.

Granger Causality & Seasonal Adjustment

One decision that we often have to make when modelling with time-series data is whether to use "seasonally adjusted" data, or the original (unadjusted) data. In some cases the decision is effectively made for us - only the seasonally adjusted data are ...

Cluster analysis in the classroom

I am a guest at the New School's Journalism + Design program this semester. The students conducted interviews about the question of what makes someone famous. Their interviewees were asked to name five famous people. We had images of these people up on the wall. Then, we put the pictures into clusters. We tried two different ways of doing it. At the end, we compared our result to what a…

An easy way to approximate a cumulative distribution function

Evaluating a cumulative distribution function (CDF) can be an expensive operation. Each time you evaluate the CDF for a continuous probability distribution, the software has to perform a numerical integration.

For yesterday, the most perceptive comment came from Slugger: Rabbit Angstrom is a perfect example of the life that the Buddha warns against.
