Data Science: The End of Statistics? As I see newspapers and blogs filled with talk of “Data Science” and “Big Data” I find myself filled with a mixture of optimism and dread. Optimism, because it means statistics is finally a sexy field. Dread, because statistics is being left on the sidelines. The very fact that […]

Every paper going to a biomedical journal has the formulaic Table 1: it's something I've done time and time again- and had to revise, time and time again. Since it's ubiquitous and highly formulaic, it seems like an ideal candidate for automating with ...

I’ve been showing my new favourite toys to just about anyone foolish enough to actually engage me in conversation. I described how my shiny new set of non-transitive dice work here, complete with a map showing all the relevant probabilities. All was neat and tidy and wonderful until fellow ecologist, Aaron Ball, tried to burst […]

We're almost done with the book review! I've received hundreds of fan mail imploring that I continue, so I will. After which, I'll put the book reviews on hold for a bit and continue with my journey down the API road. That journey will also explore som...

Someone sent me an email with the subject line “A terrible infographic,” and it went on from there: “Given some of your recent writing on infovis, I thought you might get a kick out of this . . .
