2007 Season Week 1 - Win Probabilities and Expected Wins

Monday night games now added

The following table lists the probabilities that the home team would win each game given the rushing averages, passing averages (includes sack yards lost and sacks as pass attempts), sack rates, third down conversion rates, penalty yards, and interception and fumble rates (by number of completions and rushing plays) for both teams. A logistic regression model trained on 1996-2006 data computes the probabilities. The final score margin is Home team points - Away team points. The sum of these probabilities of victory form the expected win totals in the second table.

* That 54-yard Hail Mary to Antwan Randel El is removed from the stats because it was a random play that inflated Jason Campbell's passing average by 50%. Now that I'm doing these stats live, I hope to be able to catch plays like this throughout the season and remove them from my data. Unfortunately, it's too prohibitive to go back and comb my 1996-2006 data. So be aware that the noise does exist in my training data. And I should point out that I am a Dolphins fan.
