We have covered a lot of material in this book. We have shown how applying mathematics can improve the performance of baseball, football, and basketball teams. We have learned how to evaluate teams and players and determine the probabilities of interesting events such as consecutive no-hitters. We have also gained an understanding of how sports gambling works. In this chapter we will review the important mathematical tools that we have used in our analysis.
The Use of Regression
Throughout the book, we have used regression to try to understand how various team statistics impact team performance. Often we tried to predict a dependent variable (such as Runs Scored, or an NFL team's points for and against) from team statistics ...
