I just redid the regression. I probably don't have time to post everything tonight, but here are a few observations.
1. The perfect Vanderjagt year really threw off the data. His zero miss distance skewed the entire model. I excluded his '03 season for the redo of the regression.
2. By using a natural log of the accuracy as the dependent variable, the relationship between kick accuracy and attempt distance is more linear.
3. But by excluding Vanderjagt's perfect season and by using the ln(accuracy) model, the results are very different. The difference between the best and worst kickers may be several times larger than I previously estimated. The relative rankings among the kickers are not drastically different however.
4. Surprisingly, neither warm weather or indoor kickers were significant factors.
More to follow.
