I am a big fan of NCAA football. I found that in the past weeks the cold-blooded computer rankings are more accurate than the poll rankings(BCS, Harris Poll and USA Today). And they are pretty good in predicting the game results, such as the fall of Oklahoma last week.

Data and plotting
Those ranking data are available on ESPN’s website (and they are well structured data and easy to grab). I subtracted the 6 computer rankings by the overall ranking and drew those differences on a scatter plot.
-Alabama seems to have more chance to take LSU’s place.
-Although Michigan State beat Wisconsin last week, the computers still don’t favor it.
-Auburn looks very promising.
-Oklahoma State is highly possible to become #2.
One complaint about the computer ranking
I don’t like the averaging method of the 6 computer rankings used by BCS. Transformation and factor analysis may make full use of the information - SAS’s user guide provided a detailed solution by PROC PRINQUAL and PROC FACTOR.
