The updated computer computer rankings, including RPI, are avaible on my website http://vortex.bd.psu.edu/~rutter/WomensHockey/0405WomensD1Rankings.html. Here are this weeks top ten:
1 Minnesota
2 Dartmouth
3 Minnesota-Duluth
4 Harvard
5 New Hampshire
6 Wisconsin
7 St. Lawrence
8 Princeton
9 Brown
10 Ohio State
Mercyhurst drops out of the top 10, while Brown slides in at number 9. Harvard took a little tumble, but their first two games were against weak opponents. UMD jumped up from 7th, after two wins at UW.
Check out the web page for other rankings as well, including RPI. Things are very early, but it is interesting to note how the ranking systems compare this early in the season.
Last week, Patman made the comment that he wasn't quite sure if he liked the Bayesian approach to the current ranking system, as it adds bias to the results. As a Bayesian, I don't share those same concerns, since I feel that it is important to use all of the infromation that is available to me when doing a statistically analysis. That information includes last year's perfomances. The model is set-up in such a way that as more results from this year enter the model, the data will overwhelm the prior, and the bias will be little, if any. We will be able to see the effects of this bias as the season goes on. At my website, the KRACH rankings are not Bayesian, and KRACH ranks New Hampshire number 1 for comparision. The bias of Bayesian estimates will be an argument that will continue to rage among statisiticans unitll all the non-Bayesians are converted :). It is interesting to note that Mease-Rutter closely mirrors the USCHO.com poll, an indication how the human pollsters are also using previous results to rank the teams.
