Full Brier scorecard with the Murphy decomposition.

Fields

total_predictions: usize

Total predictions ever recorded.

resolved: usize

Predictions resolved against reality.

unresolved: usize

Predictions still awaiting resolution.

avg_brier_score: f64

Average Brier score over resolved predictions (lower is better).

reliability: f64

Reliability term — mean squared gap between predicted probability and observed rate within bins. 0 = perfectly calibrated.

resolution: f64

Resolution term — how well predictions separate outcomes. Higher is better (upper bounded by uncertainty).

uncertainty: f64

Uncertainty — base-rate variance ō(1 − ō). The difficulty ceiling.

skill_score: f64

Brier skill score vs. climatology (1 = perfect, 0 = no better than always predicting the base rate, negative = worse).

calibration_bins: Vec<CalibrationBin>

Decile calibration bins (predicted probability → observed rate).

calibration_gap: f64

Historical rolling calibration gap used for adjustments.

perfect_calibration: bool

Whether the model is essentially perfectly calibrated.

good_calibration: bool

Whether calibration is good (Brier < 0.15).
