This week I’ll start my Bayesian Statistics master’s course at the Collegio Carlo Alberto. I realized that some of last year students got PhD positions in prestigious US universities. So I thought that letting this year’s students have a first grasp of some great Bayesian papers wouldn’t do harm. The idea is that in addition to the course, […]

Sigmund Freud vs. Stewart Lee; Dick advances

Yesterday‘s thread was won by Slugger, who wrote: I accidentally swallowed a stelazine capsule and have seen that Grandma Moses is in fact a reptilian lifeform without the ability to vocalize. My vote goes to PKD. Where did that light switch come from, anyway? I could’ve sworn it was a pull cord. . . .

Brian Hunt: He was the #1 math team kid in our team (Montgomery County, Maryland). I think he came in first place in the international olympiad the next year (yup, here’s the announcement).

Grandma Moses vs. Philip K. Dick (2); Gandhi advances

Yesterday’s most relevant comment came from Ben: Gandhi would have a far more interesting things to say about the current state of world politics, etc. The issues that Gandhi was known for (de-colonization, passive resistance) remain immensely relevant but with very different parameters than the 1920’s-1940’s. By contrast, Mother Teresa’s main mission (serving the poor) […] The post Grandma Moses vs. Philip K. Dick (2); Gandhi advances appeared first on…

Mohandas Gandhi (1) vs. Mother Teresa (4); Hobbes advances

March 15, 2015

For yesterday, we didn’t get much in the way of comments, so I’ll have to go with this comment by Jonathan: Hobbes is the Arnold Schwarzenegger of philosophers. Any time someone feels he’s been killed off, he’ll be back. Tolstoy is the Buster Keaton of novelists. Widely admired, widely studied, and just about obsolete in […] The post Mohandas Gandhi (1) vs. Mother Teresa (4); Hobbes advances appeared first on…

First off, I just want to say I made a mistake yesterday dropping Alan Turing in favor of Ed Wood. As Zbicyclist put it, “Ed Wood’s best thoughts are probably on the screen.” And that’s not good at all! So, sorry for eliminating one of the exciting speakers from the list. I’m also thinking of […] The post Thomas Hobbes vs. Leo Tolstoy; Rock advances appeared first on Statistical Modeling,…

De-weaponizing reproducibility

March 13, 2015

A couple of weeks ago Roger and I went to a conference on statistical reproducibility held at the National Academy of Sciences. The discussion was pretty wide ranging and I love that the thinking about reproducibility is coming back to statistics. There was pretty widespread support for the idea that prevention is the right way to approach
