This repository contains some scripts and data for sabermetrics (analysis of baseball statistics.)

Octopress Blog Posts

I am using these scripts to write a series of Octopress blog posts. These are listed here, along with the scripts that correspond to each post.

Kernel Density Functions and the Oakland Athletics

  • The file AthleticsABKDE.py generates KDEs for at-bats, analyzed in this first post.

Using Multivariate KDEs to Examine How Baseball Is Changing

  • The file AllTeams.py generates univariate and multivariate KDEs for multiple batting stats, for all teams

  • The file HRVariance.py contains variance and correlation plots for home runs and how they change, or are correlated with other variables

Data

I've put together some data files, contained in the data/ directory. This consists of batting statistics for individual teams, plus a master batting stats file that contains batting statistics for all teams.

  • The data are all in CSV format and come from Baseball-Reference.com

  • The file CombineEverybody.py combines data for all teams into the master batting stats file.
