VT/BC Statistical Comparison
What do the numbers say will happen this weekend?
This week's statistical comparison will include the following ratings and, if available, the statistical prediction based on the rating:
- Massey Ratings (http://www.masseyratings.com/). These are Massey's own ratings which include scoring margin, not to be confused with his BCS rankings which will not post until they achieve some level of credibility during the season.
- Sagarin (http://www.kiva.net/~jsagarin/sports/cfsend.htm), perhaps the most popular of all statistical rankings. The first is his ELO ranking, which is used for the BCS and fits their criteria; the second is PREDICTOR which takes into account scoring margin and is much more accurate for determining how good teams are.
- Fremeau Index (http://bcftoys.blogspot.com/2009/09/week-2-fei-ratings.html) as suggested by furrer4heisman. From the site this syetm is "based on drive-based Game Efficiency data that rewards playing well against good teams, win or lose, and punishes losing to poor teams more harshly than it rewards defeating poor teams" where Game Efficiency is "Measurement of the success rate of a team scoring and preventing opponent scoring during the Competitive Possessions of a game as GE = ((Points For - Points Against)/7) / (Total Competitive Possessions/2)" and competitive possesions are basically possessions that potentially matter.
Here is how we stack up:

Unfortunately I underestimated Boston College and it appears that this one is closer than I hoped for. Let's go Hokies!
