Bayes-respecting experimental design and other things

Dan Lakeland writes: I have some questions about some basic statistical ideas and would like your opinion on them: 1) Parameters that manifestly DON’T exist: It makes good sense to me to think about Bayesian statistics as narrowing in on the value of parameters based on a model and some data. But there are cases […]The post Bayes-respecting experimental design and other things appeared first on Statistical Modeling, Causal Inference,…

Matching Madness: Causal Inference in Political Methodology

If the 2013 Methods Meetings are any indication, political methodologists really want to talk about causal inference. Four panels in the conference program actually have the term “causal inference” in their title—indeed, the word “causal” actually appears 13 times in the program—and at least two more panels were directly about how to draw causal inferences […]

Know your data 13: no-tracking technologies

July 25, 2013

I have been highlighting some cases of analysts doing a masterful job in taking apart claims made in the media. Here is another example from Bruce Schneier, the national security expert. In June 2013, a Who’s Who list of telecom and technology companies, such as Verizon, AT&T, Google and Facebook, was busted for passing customer data to the National Security Agency in its domestic surveillance program. This episode invites scrutiny…

Are women three times more likely to wear red or pink when they are most fertile? No, probably not. But here’s how hardworking researchers, prestigious scientific journals, and gullible journalists have been fooled into believing so. The paper I’ll be talking about appeared online this month in Psychological Science, the flagship journal of the Association […]The post Too Good To Be True: The Scientific Mass Production of Spurious Statistical Significance…

Here are two recent profiles of me: Oracle's Profit: "Beyond Big Data" (link) ASA News (link) In the second one, they asked me to give advice to people who are interested in getting into data visualization. Here is my answer: Keep sketching, and keep trashing. Settle your story and then find the tools, never the other way around. Hate the default. Imagine your audience. If you don’t have an audience,…

THE FIVE: Jeff Leek’s Challenge

Jeff Leek, over at Simply Statistics asks an interesting question: What are the 5 most influential statistics papers of 2000-2010? I found this to be incredibly difficult to answer. Eventually, I came up with this list: Donoho, David (2006). Compressed sensing. IEEE Transactions on Information Theory. 52, 1289-1306. Greenshtein, Eitan and Ritov, Ya’Acov. (2004).

The other day, Nicholas Christakis wrote an article in the newspaper criticizing academic social science departments: The social sciences have stagnated. . . . This is not only boring but also counterproductive, constraining engagement with the scientific cutting edge and stifling the creation of new and useful knowledge. . . . I’m not suggesting that […]The post Christakis response to my comment on his comments on social science (or just…
