Module statistical 

Statistical regression detection algorithms.

Provides:

• StatRegressionDetector — z-score + relative-change detector with Welford online mean/variance estimation.
• CusumDetector — CUSUM sequential change-point detection algorithm.

These supplement the performance-baseline detector in detector.rs with algorithms operating directly on a streaming sequence of scalar metric values rather than on full profiling reports.

Structs

CusumAlert

Alert emitted by CusumDetector when a change point is detected.

CusumDetector

CUSUM (Cumulative Sum) sequential change-point detector.

StatBaselineStats

Statistical summary of a reference sample set.

StatRegressionConfig

Configuration for StatRegressionDetector.

StatRegressionDetector

Statistical regression detector for a single scalar training metric.

StatRegressionEvent

A single detected regression event.

Enums

ChangeDirection

The direction of a CUSUM change-point alert.

StatRegressionDirection

Indicates the direction that is considered “bad” for a metric.

StatRegressionSeverity

Severity class for a detected regression event.
