It's February, so I'm Trying to Find things to Post On. Therefore You're Going to Get Some Simple Regression Tests from the 2008 MLB Season.
The Major High Outlier: Rangers with an On Base Percentage of .354 and 79 Wins
The Low Outlier: Angels with an On Base Percentage of .330 and 100 Wins
Formula: On Base Percentage = 0.288506 + (0.000549) * Wins
ReFangled Formula: Wins = (OBP + 0.288506) / (0.000549)
Fun Math Time
The regression line appears to have magentic repellent as only three of the teams really come close to the line, but we move on. If I want the Yanks to win 100 games this year the ole formula suggest they'll need and On Base Percentage of .343, which would be a slight improvement from last year. Meanwhile if I think that the Devil Rays are going to have an on Base Percentage of say .330, than they would be expected to fall to 76 games this year.
