1:30 PM | Is Outrage Over the Facebook Mood Manipulation Study Ignorance or Anti-Science?
By now, you’ve probably heard about the latest controversy coming from Facebook – a researcher internal to Facebook, along with two university collaborators, recently published a paper in PNAS[1] that included an experimental manipulation of mood. Specifically, the researchers randomly assigned about 700,000 Facebook users to test an interesting causal question: does the emotional content […]Related articles from NeoAcademic:When You Are Popular on Facebook, Strangers Think […]

1:30 PM | “Being an informed Bayesian: Assessing prior informativeness and prior–likelihood conflict”
Xiao-Li Meng sends along this paper (coauthored with Matthew Reimherr and Dan Nicolae), which begins: Dramatically expanded routine adoption of the Bayesian approach has substantially increased the need to assess both the confirmatory and contradictory information in our prior distribution with regard to the information provided by our likelihood function. We propose a diagnostic approach […] The post “Being an informed Bayesian: Assessing prior informativeness and […]

Schekman hatte kurz nach der Verleihung des Nobelpreises für Medizin 2013 mit seinen klaren Äußerungen […]

1:20 PM | “Who’s bigger”—the new book that ranks every human on Wikipedia—is more like Bill Simmons than Bill James
I received a copy of “Who’s Bigger?: Where Historical Figures Really Rank,” by Steven Skiena, a computer scientist at Stony Brook University, and Charles Ward, and engineer at Google. Here’s the blurb I gave the publisher: Skiena and Ward provide a numerical ranking for the every Wikipedia resident who’s ever lived. What a great idea!

3:28 PM | Who invented the Metropolis algorithm?
Paul Alper writes: I found this at the 15:57 mark of one of Bill Press’s videos but do not know if this bit of history is well known in the MCMC universe. This is Marshall Rosenbluth criticizing Metropolis (and others). The text is taken from an interview of Rosenbluth in 2003 by Kai-Henrik Barth: Barth: […] The post Who invented the Metropolis algorithm? appeared first on Statistical Modeling, Causal Inference, and Social Science.

1:31 PM | Out of the Lab & Into the Mouth
Many pitfalls await the undergraduate in the laboratory. Bunsen burners! Liquid nitrogen! The slack work ethic of one’s peers! The dreaded group projects! But the most common risk budding researchers face are the rubber glove-donners themselves, perpetrator and victim rolled into one lab coat-wearing pipetter, armed and often dangerous with great knowledge but little know-how.

4:03 PM | Scott Adams blogging
Some of my commenters (you know who you are) demand more Scott-Adams-related content. So I went over to the Dilbert blog and found two interesting recent items: The Pivot: I’m not particularly interested in the topic (rich guys getting richer) but Adams usefully deploys statistical thinking in this one (“Success simply can’t be predicted to […] The post Scott Adams blogging appeared first on Statistical Modeling, Causal Inference, and Social Science.

1:00 PM | Useless Algebra, Inefficient Computation, and Opaque Model Specifications
I (Bob, not Andrew) doubt anyone sets out to do algebra for the fun of it, implement an inefficient algorithm, or write a paper where it’s not clear what the model is. But… Why not write it in BUGS or Stan? Over on the Stan users group, Robert Grant wrote Hello everybody, I’ve just been […] The post Useless Algebra, Inefficient Computation, and Opaque Model Specifications appeared first on Statistical Modeling, Causal Inference, and Social Science.

1:43 PM | Quantifying luck vs. skill in sports
Trey Causey writes: If you’ll permit a bit of a diversion, I was wondering if you’d mind sharing your thoughts on how sabermetrics approaches the measurement of luck vs. skill. Phil Birnbaum and Tom Tango use the following method (which I’ve quoted below). It seems to embody the innovative but often non-intuitive way that sabermetrics […] The post Quantifying luck vs. skill in sports appeared first on Statistical Modeling, Causal Inference, and Social Science.
