Forecast vs result

Surprise Games

The games that went furthest from what this model expected. "Surprising" here means surprising to this forecast, which is not perfectly calibrated, not necessarily to everyone watching.

How surprise is measured

Unexpected winners
Ranked by the pregame win probability the forecast gave the team that won, lowest first. The technical measure is −ln(p): 0.22 for an 80% winner, 0.69 for a coin flip, 2.30 for a 10% winner. Probabilities are bounded at 0.0001 inside the logarithm only, to keep it finite; displayed probabilities are the stored ones.
Margin misses
Ranked by the absolute difference between the forecast home margin and the final home margin, in points. A forecast of a 5-point home win followed by a 20-point home loss is a 25-point miss. This is a separate ranking: a big margin miss can still have the right winner.
Most recent
Games where the forecast favorite lost, newest first.
Which games
Every completed game with a stored forecast, one forecast per game (see Methodology). Games not yet played are never included.
