I just found a fun food themed dataset that I’d never heard about and that I thought I’d share. It’s from a project called What’s on the menu where the New York Public Library has crowdsourced a digitization of their collection of historical ...

Not surprisingly, this year’s UseR! conference was a great event with heaps of talented researchers and R-developers showing off the latest and greatest R packages. (A surprise visit from Donald Knuth didn’t hurt either.) What was extra great thi...

Today I’m extraordinarily pleased because today I solved an actuall real world problem using R. Sure, I’ve solved many esoteric statistical problems with R, but I’m not sure if any of those solutions have escaped the digital world and made some impact ex silico. It is now summer and in Sweden that means that many people tend to overhaul...

I recently wrapped up a version of my R function for easy Bayesian bootstrappin’ into the package bayesboot. This package implements a function, also named bayesboot, which performs the Bayesian bootstrap introduced by Rubin in 1981. The Bayesian bootstrap can be seen as a smoother version of the classical non-parametric bootstrap, but I prefer seeing the classical...

Bayesian data analysis is cool, Markov chain Monte Carlo is the cool technique that makes Bayesian data analysis possible, and wouldn’t it be coolness if you could do all of this in the browser? That was what I thought, at least, and I’ve now made bayes.js: A small JavaScript library that implements an adaptive MCMC sampler and a...

Romantic kissing is a cultural universal, right? Nope! At least not if you are to believe Jankowiak et al. (2015) who surveyed a large number of cultures and found that “sexual-romantic kissing” occurred in far from all of them. For some reasons the paper didn’t include a world map with these kissers and non-kissers plotted out. So, with the...

The BASIC programming language was at one point the most widely spread programming language. Many home computers in the 80s came with BASIC (like the Commodore 64 and the Apple II), and in the 90s both DOS and Windows 95 included a copy of the QBasic IDE. QBasic was also the first programming language I encountered (I used...

This is a screencast of my UseR! 2015 presentation: Tiny Data, Approximate Bayesian Computation and the Socks of Karl Broman. Based on the original blog post it is a quick’n’dirty introduction to approximate Bayesian computation (and is also, in a sense, an introduction to Bayesian statistics in general). Here it is, if you have 15 minutes to...
