These ratings are based on the Bradley-Terry method. Ratings are compiled for NCAA FBS (Division 1-A) football and Division 1 basketball. The basic method considers only win/loss results and home field advantage; the margin-aware method is modified to use margin of victory as well with diminishing returns for blowouts.

Home field and a small adjustment to produce more realistic win probabilities for teams at the extreme ends of the rating scales have only been applied to the ratings starting with 2011 football. At this time, I do not intend to roll these changes into the older ratings. Details of the method are available here.
