Struct BrierScoreTracker 

pub struct BrierScoreTracker { /* private fields */ }

Brier score calibration tracker.

Computes Brier score = (1/n) * Σ(p - o)² where p is predicted probability and o is actual outcome (0 or 1). Perfect calibration yields Brier score = 0.

Implementations

impl BrierScoreTracker

pub fn new() -> Self

Create a new empty tracker.

pub fn record(&mut self, predicted_probability: f64, was_incompatible: bool)

Record a prediction and its outcome.

pub fn brier_score(&self) -> f64

Get the current Brier score (0 = perfect, 1 = worst).

pub fn count(&self) -> usize

Get number of predictions recorded.

pub fn is_calibrated(&self, threshold: f64) -> bool

Check if predictions are well-calibrated (Brier score below threshold).

pub fn reset(&mut self)

Reset the tracker.

pub fn metrics(&self) -> BrierScoreMetrics

Get calibration metrics.
