May14

A dataset containing play-by-play data from MLBAM GameDay and processed by
<code>openWAR</code> for all games on May 14, 2013.

datasets

This package serves two primary purposes: 1) it facilitates the
computation of openWAR, a fully open-source implementation of Wins Above
Replacement (WAR) that could serve as a reference implementation for the
sabermetric community; and 2) it downloads raw XML files from the MLBAM
GameDay web application and processes them into play-by-play data in a
tabular format. This play-by-play information is similar in spirit, though
not in syntax, to play-by-play data made available by Retrosheet. Those
interested in the modeling choices that we have made in our computation of
openWAR should consult our JQAS or arXiv paper on that subject. This
implementation of openWAR includes functions for constructing interval
estimates of WAR for each player, as well as comparing openWAR point
estimates to those of Baseball-Reference.com's rWAR.
