“Derek Jeter was OK”

Tom Scocca files a bizarrely sane column summarizing the famous shortstop’s accomplishments: Derek Jeter was an OK ballplayer.

Luck vs. skill in poker

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).

Stan World Cup update

The other day I fit a simple model to estimate team abilities from World Cup outcomes.
