NBA prediction record

Every NBA prediction stays on this page once the game finishes, right or wrong. So far this season the model has named the winner in 95 of 139 games (68%). Its own figures said to expect about 91.5 correct, so it is running 3.5 ahead of what it forecast.

Calibration: when we said 70%, did it happen 70% of the time?

Each dot groups games by the chance the model gave its predicted winner. A dot on the dashed diagonal means those chances came true exactly as often as stated; bigger dots hold more games. The accuracy score (average squared error, lower is better) is 0.200, against 0.250 for a coin flip.

Early-season groups are small, so single results move the dots a lot. The chart fills in as the season goes on.
