Dan Kahan writes: We all know it’s ridiculous to be able to go on an fMRI fishing trip & resort to post hoc story-telling to explain the “significant” correlations one (inevitably) observes (good fMRI studies *don’t* do this; only bad ones do– to the injury of the reputation of all the scholars doing good studies [...]

Why settle for just one realisation of this year’s UEFA Euro when you can let the tournament play out 10,000 times in silico? Since I already had some code lying around from my submission to the Kaggle hosted 2010 Take on the Quants challenge, I figured I’d recycle it for the Euro this year. The

Few people have influenced the face of information graphics like Nigel Holmes. I am honored to not only present his very extensive and detailed list of influences here, but also do so on the occasion of his upcoming 70th birthday on June 15, 2012. Nigel Holmes has recently been the subject of discussions in information visualization because of the role and potential benefit of chart junk. His work has been…
Yelp put a data set online for people to play with, including reviews, star ratings, etc. This could be a really neat data set for a student project. The data they have made available focuses on the area around 30 universities. My alma mater is one o...

One of the most famous sayings about statistics is the line: “There are three types of lies, lies, damned lies and statistics.” This was stated by author Mark Twain (Samuel Clements) and quoted by British statesman Benjamin Disraeli. There is … Continue reading →
While speeding up some code the other day working on a project with a colleague I ended up trying Rcpp for the first time. I re-implemented the cosine distance function using RcppArmadillo relatively easily using bits and pieces of code I found scatter...

Here’s some psychology research that’s relevant to yesterday’s discussion on working-class voting. In a paper to appear in the journal Cognitive Science, Andrei Cimpian, Amanda Brandone, and Susan Gelman write: Generic statements (e.g., “Birds lay eggs”) express generalizations about categories. In this paper, we hypothesized that there is a paradoxical asymmetry at the core of [...]
Our latest paper in PLoS Computational Biology is out.The project spanned over 2 years starting at the end of my first year of postdoctoral training until now. It has been a truly collaborative endeavor across institutions but also across sub-disciplin...
The last day of EuroVis brought back the sunshine we had seen yesterday, but had missed for the first half of the conference. This was a short day, with only one paper session and the keynote. The latter proved to be quite controversial and interesting. Papers A Taxonomy of Visual Cluster Separation Factors by Michael Sedlmair, Andrada Tatu, Tamara Munzner, and Melanie Tory described work to classify clustering algorithms using…

Stephen Olivier points me to this horrible, horrible news article by Jonathan Haidt, “Why working-class people vote conservative”: Across the world, blue-collar voters ally themselves with the political right . . . Why on Earth would a working-class person ever vote for a conservative candidate? This question has obsessed the American left since Ronald Reagan [...]
I missed a few of the papers I wanted to see today, but there were again some interesting ones. The big event of the day was of course the social event at a Heuriger. ClockMap: Enhancing Circular Treemaps with Temporal Glyphs for Time-Series Data by Fabian Fischer, Johannes Fuchs, and Florian Mansmann is an interesting approach for finding temporal trends in a large amount of data. The visual metaphor is…
![\STATE [algorithmic package]](http://xianblog.files.wordpress.com/2012/06/pi10000.jpg?w=450&h=450)
I fought with my LαTεX compiler this morning as it did not want to deal with my code: looking on forums for incompatibilities between beamer and algorithmic, and adding all kinds of packages, to no avail. Until I realised one \STATE was missing: (This is connected with my AMSI public lecture on simulation, obviously!) Filed [...]
