Leverage Index and WPA calculators?

[Bryan Cole]

Hey guys,

Just started working with the Retrosheet and BDB databases (thanks to everyone behind the tutorials).  I've figured out how to compile box score-level statistics (IP, H, R, K, BB, etc.) and some basic ratios (OBP, SLG) from the Retrosheet games.  I was wondering if anyone out there had managed to produce WPA, aLI, or some of the other more advanced stats that they were willing to share.

Thanks,

-Bryan
