Decision Trees, R, and Sabermetrics · 05/02/2007 11:43 AM, Analysis

The baseball guys LOVE their stats, and stats guys tend to like baseball. They even have their own name for the use of statistics in baseball: Sabermetrics. A very compelling story of how an organization can benefit from the use of statistical measures is Moneyball by Michael Lewis about the rise of the Oakland As.

And Tom Dierickx in his blog Data-For-All shows a good example of analyzing baseball stats in R to answer a specific question. The best part is that its a quick and concise example of how to create and review a regression/decision tree in R.

Predicting April OPS from Spring Training Stats and the followup Predicting April OPS from Spring Training Stats Revisited are both worth a read.

I tend to glaze over the moment I hear the phrase “anything-ball”, so the fact that I enjoyed these shows that even organized team sports can be made interesting with enough ketchup.
