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…

Count data are less useful than you think

A lot of Big Data analyses default to analyzing count data, e.g. number of searches of certain keywords, number of page views, number of clicks, number of complaints, etc. Doing so throws away much useful information, and frequently leads to bad analyses. *** I was reminded of the limitation of count data when writing about the following chart, which I praised on my sister blog as a good example of…

Infographics do not have to be "data ornaments" (link). Once in a blue moon, someone finds the right balance of pictures and data. Here is a nice example from the Wall Street Journal, via ThumbsUpViz. Link to the image What...

“Derek Jeter was OK”

Tom Scocca files a bizarrely sane column summarizing the famous shortstop’s accomplishments: Derek Jeter was an OK ballplayer. He was pretty good at playing baseball, overall, and he did it for a pretty long time. . . . You have to be good at baseball to last 20 seasons in the major leagues. . . […]

Poker math showdown!

In comments, Rick Schoenberg wrote: One thing I tried to say as politely as I could in [the book, "Probability with Texas Holdem Applications"] on p146 is that there’s a huge error in Chen and Ankenman’s “The Mathematics of Poker” which renders all the calculations and formulas in the whole last chapter wrong or meaningless […] The post Poker math showdown! appeared first on Statistical Modeling, Causal Inference, and Social…

Luck vs. skill in poker

The thread of our recent discussion of quantifying luck vs. skill in sports turned to poker, motivating the present post. 1. Can good poker players really “read” my cards and figure out what’s in my hand? For a couple years in grad school a group of us had a regular Thursday-night poker game, nickel-dime-quarter with […] The post Luck vs. skill in poker appeared first on Statistical Modeling, Causal Inference,…

Josh Miller writes: I came across your paper in the Journal of Management on unreplicable research, and in it you illustrate a point about the null hypothesis via the hot hand literature. I am writing you because I’d like to move your current prior (even if our work uses a classical approach). I am also […] The post Understanding the hot hand, and the myth of the hot hand, and…

NFL players keep getting bigger and bigger

Aleks points us to this beautiful dynamic graph by Noah Veltman showing the heights and weights of NFL players over time. The color is pretty but I think I’d prefer something simpler, just one dot per player (with some jittering to handle the discrete reporting of heights and weights). In any case, it’s a great […] The post NFL players keep getting bigger and bigger appeared first on Statistical Modeling,…
