Limits of statistics, and by extension data science, as illustrated by Deflate-gate

A number of readers sent me Warren Sharp's piece about the ongoing New England Patriots' deflate-gate scandal (link to Slate's version of this) so I suppose I should say something about it. For those readers who are not into American football, the Superbowl is soon upon us. New England, one of the two finalists, has been accused of using footballs that are below the weight requirements on the rulebook, hence…

Debate on using margin of error with non-probability panels

Tomorrow (Thurs 22 Jan) at 2pm, I’m participating (along with Jane Tang, John Bremer, Nancy Brigham, and Steve Mossup) on an online discussion, moderated by Annie Pettit, on the above topic. Here’s the description: Most marketing researchers know that using Margin of Error with convenience samples, non-probability samples, and online research panels is inappropriate. However, […] The post Debate on using margin of error with non-probability panels appeared first on…

Stan comes through . . . again!

Erikson Kaszubowski writes in: I missed your call for Stan research stories, but the recent post about stranded dolphins mentioned it again. When I read about the Crowdstorming project in your blog, I thought it would be a good project to apply my recent studies in Bayesian modeling. The project coordinators shared a big dataset […] The post Stan comes through . . . again! appeared first on Statistical Modeling,…

Phil writes: This is kind of fun (at least for me): You would probably guess, correctly, that membership in the US Chess Federation is lower than its peak. Guess the year of peak membership, and the decline (as a percentage) in the number of members from that peak. My reply: I don’t know, but I’d […] The post Try answering this question without heading to Wikipedia appeared first on Statistical…

The latest episode in my continuing effort to use non-sports analogies

December 14, 2014
By

In a unit about the law of large numbers, sample size, and margins of error, I used the notorious beauty, sex, and power example: A researcher, working with a sample of size 3000, found that the children of beautiful parents were more likely to be girls, compared to the children of less-attractive parents. Can such […] The post The latest episode in my continuing effort to use non-sports analogies appeared…

Who should write the new NYT chess column?

December 8, 2014
By

Matt Gaffney gives these “three essential characteristics” for writing “a relevant, interesting weekly chess column” in 2014: 1. It must be written by someone who is deeply involved in the chess world. Summaries of information that is already available online won’t cut it anymore. And since newspapers can’t afford to send columnists around the world […] The post Who should write the new NYT chess column? appeared first on Statistical…

Times have changed (sportswriting edition)

The name Tom Boswell came up in a recent comment thread and I was moved to reread his 1987 article, “99 Reasons Why Baseball Is Better Than Football.” The phrase “head injury” did not come up once. Boswell refers a few times to football’s dangerous nature (for example, “98. When a baseball player gets knocked […] The post Times have changed (sportswriting edition) appeared first on Statistical Modeling, Causal Inference,…

Ray Could Write

Now he is scattered among a hundred cities And wholly given over to unfamiliar affections, To find his happiness in another kind of wood And be punished under a foreign code of conscience. . . . You were silly like us; your gift survived it all: For chess makes nothing happen: it survives In the […] The post Ray Could Write appeared first on Statistical Modeling, Causal Inference, and Social…

2 on chess

Is it really “often easier to win a rematch than to defend a championship”? The quoted bit above comes from Tyler Cowen, writing about the Anand/Carlsen world championship rematch. I’m still not used to the idea of a new world championship match every year but I guess why not? Anyway, here’s my question. Tyler Cowen […] The post 2 on chess appeared first on Statistical Modeling, Causal Inference, and Social…
