Our Ratings
The Win-Loss Based Rating uses only win-loss, schedule,
and venue (home/away) data. Thus, margin of victory is not a
factor. The downside of such an approach is that all games are
reduced to a single bit of data. The upside is that it is not
possible to compensate for a loss in one game by running up the
score in another. Given that the objective of the game is to win
and to do so against quality opponents, we feel that the
Win-Loss Based Rating is the best measure of how well a team
fulfills the game's primary objectives. Note that the
Win-Loss Based Rating has no subjective inputs. See our paper
for a lengthy description of how this was achieved.
The Hybrid Rating consists of a simple linear
combination of our Win-Loss Based Rating and our Score-Based
Rating. The latter component uses only scores, schedule, and
venue (home/away) data. The only subjective input is the relative
weight given to the two components. Individually, the component
ratings themselves have no subjective inputs. Note that we do not
separately publish the Score-Based Rating, but it is the basis
for our score and win predictions, and we hope at some point in
the future to publish in complete detail the methods employed in
generating them.
