Pythagorean winning percentage is an estimate of a team's winning percentage given their runs scored and runs allowed. Developed by Bill James, it can tell you when teams were a bit lucky or unlucky. It is calculated by

(Runs Scored)^1.83
---------------------------------------------------------
(Runs Scored)^1.83 + (Runs Allowed)^1.83

The traditional formula uses an exponent of two, but this has proven to be a little more accurate.
