July 22, 2013

At three separate recent non-American conferences, I heard three separate European econometricians refer to generalized method of moments (GMM) as a "strange American estimator." Needless to say, that raised my eyebrows. One doesn't hear that phrase to...

When Hansel comes out to save the day preventing "Derek [Zoolander] to off the prime minister of Micronesia", the evil Jacobim Mugatu says "It's that damn Hansel – He's so hot right now!".Quite in a similar fashion(?), it seems as though in the ...

July 22, 2013

Statistical Methods and Data Skepticism Data analysis today is dominated by three paradigms: null hypothesis significance testing, Bayesian inference, and exploratory data analysis. There is concern that all these methods lead to overconfidence on the part of researchers and the general public, and this concern has led to the new “data skepticism” movement. But the […]The post My talks that were scheduled for Tues at the Data Skeptics meetup and…

The inverse CDF method for simulating from a distribution

There are many techniques for generating random variates from a specified probability distribution such as the normal, exponential, or gamma distribution. However, one technique stands out because of its generality and simplicity: the inverse CDF sampling technique. If you know the cumulative distribution function (CDF) of a probability distribution, then [...]

GED Viz, A Data Storytelling Tool

I had the honor and pleasure to keynote an event in Berlin recently that introduced a new visualization tool to the world, GED Viz. What makes it stand out from other web-based visualization tools is its focus on particular data, and the ability to create not just individual views, but little stories. GED stands for Global Economic Dynamics, which explains where the motivation for the project actually came from: the…

They offer essentially the same set of academic departments and disciplines that they have for nearly 100 years: sociology, economics, anthropology, psychology and […]The post Defensive political science responds defensively to an attack on social science appeared first…

Do the Simpsons characters like each other?

One day, while I was walking around Cambridge, I had a random thought — how do the characters on the Simpsons feel about each other? It doesn’t take long to figure out how Homer feels about Flanders (hint: he doesn’t always like him), or how Burns feels about everyone, but how does Marge feel about Bart? How does Flanders feel about Homer? I then realized that I work with algorithms…

And also a “web application for data analysis using powerful Bayesian statistical methods.” I took a look.

The current puzzle is the last one before the summer break and not exciting enough to take along: Take the first ten digits, create five pairs out of those, and for each pair (x,y) derive the quantity (min(x,y)+1.5max(x,y)). What is the collection of pairs that maximises the product of those quantities? I wrote the following […]
