How far the model landed from the result

Every figure below compares the model's pregame projected margin to the final score. The latest week is shown; use the tabs for another season or week. Free to use and distribute, like the rest of the archive.

Error is projected margin minus final margin. Mean squared error punishes the badly missed games hardest; its square root puts that back into points, to read against the mean absolute error. Bias is the average signed error: above zero the model had home teams ahead of where they finished, below zero behind. Games the model called at 50/50 are not graded as picks.
