How to read the table:
  • Vegas Line: A NEGATIVE number implies the point spread favors the HOME team
  • Estimate: NFL Pickles' point spread prediction
  • Pred-Vegas: Subtraction of the previous two. POSITIVE implies VISITING team will cover point spread.
  • Confidence: The probability that the point spread pick is on the correct side.

If I am reading the chart right Dallas should be your pick. Unless something else is wrong.

You're right, but my spread was entered incorrectly. A minus sign mistake, yet the probability is the same. Philly is the pick. Thanks for pointing it out.

Jaime - Tried doing some reading up on how you calculate confidences. It's hard searching through old posts, but from what I gather, you have 80 different buckets that each game can fall under, and the confidence is simply how often that bucket has been correct. Am I right on this?

My hunch is that you have 8 or 10 Vegas Line columns, and 10 or 8 Estimate rows (from the model). It's irrelevant exactly how it's set up, but have you looked at smoothing the performance of the buckets? E.g. if a bucket is only hitting 75%, but all its adjacent buckets are only hitting 40%, is the 75% accurate, or could it just be noise.

I think some form of smoothing could be useful. Looking at week 2 (unofficial, I know), STL@ATL and SD@PHI both had lines of -7. Your estimates were -.2 and +3 respectively. It doesn't make sense to me that you could be more confident in the -.2 game than the +3 game.

Not trying to be critical. I've been using this site for years and love it - just want to throw some ideas out and see if you've looked at them already or want to consider them.

@jonathon you got it buddy. I do that back tested for 15 years. Your smoothing and preserving order ideas are very good ones. We should talk one day.
