About
nfelo is a prediction model built on top of 538's Elo framework that uses unique dynamics about the NFL to improve prediction accuracy. It is one of the (if not the!) most accurate public models available on the internet.
The tables below show model performance for 538, nfelo, and the Vegas line across a variety of measures. "Straight up" describes a model's ability to pick winners, "RMSE" describes a model's ability to predict the final margin of victory, and "ATS" describes a model's ability to beat the spread.
Straight up and RMSE take all games into consideration while ATS only considers games rated break-even or better. Break-even for nfelo is defined by expected value, while 538 is defined by games with a delta between projected line and market line of over 1.5.
