NCAA Div 1A Computer Rankings
Several existing
college football computer rankings employ (what I consider to be) biased strength-of-schedule
algorithms (e.g., Sagarin).
In an attempt to eliminate such biases (primarily for my own amusement), I have
developed a computer ranking program
( Visual Basic in Access ) using the algorithm described below in an attempt
to derive strength-of-schedule from
won/loss records for both the team being evaluated and that team's opponents.
| Parameter | Value | Description |
| Home Win Bonus | 0.85 | awarded for each win at home, with the premise that a team has a home field advantage |
| Away Win Bonus | 1.15 | awarded for each win away, with the premise that winning away is more difficult than winning at home |
| Home Loss Penalty | 0.4 | penalty for losing at home, with the premise that losses should be penalized and a team should win at home |
| Away Loss Penalty | 0.2 | penalty for losing away, with the premise that losses should be penalized but a loss away is not as bad as a loss at home |
| Margin for bonus | 8 | Minimum number of points by which to win to receive "style points," with the premise that winning by more than a touchdown shows some strength |
| Score Margin Bonus | 0.3 | "Style points" for winning by at least the Margin For Bonus |
| Opponent Win Multiplier | 0.333333 | Fraction of each defeated opponent's win, with the premise that some strength is shown by defeating an opponent which has a good win record |
No "style points" for win over non-Div 1A opponents.
A penalty of -1 is awarded for a loss to a non-Div 1A opponent.
