Model Performance

2025 Season · 2,996 graded predictions

In-sample data: All predictions for this season were generated after games completed (historical backfill), so metrics reflect in-sample fit rather than true out-of-sample accuracy. Metrics will become trustworthy as the current season progresses and daily ETL generates pre-game predictions.

How to Read This

Overall Accuracy — % of games where the model's favored team won.

Brier Score — measures probability calibration quality. Lower is better.

Log Loss — penalises confident wrong predictions more harshly than Brier score. Lower is better.

AUC — probability that the model ranks a random home win above a random home loss. 0.5 = no skill; 1.0 = perfect.

Calibration chart — a perfectly calibrated model's bar would exactly touch the line in every bucket.

Elo ratings — self-correcting power ratings that update after every game. 1500 is average.
