Struct DynamicThresholdDetector 

pub struct DynamicThresholdDetector { /* private fields */ }

Anomaly detector with an adaptive rolling threshold.

Supports optional seasonal awareness via hour-of-day bucketing.

Implementations

impl DynamicThresholdDetector

pub fn new(lookback: Option<usize>, k: Option<f64>) -> Self

Creates a new detector.

• lookback — rolling window size (default 100).
• k — number of standard deviations for the threshold (default 3.0).

A zero lookback is silently clamped to 1 to prevent modulo-by-zero.

pub fn with_period( lookback: Option<usize>, k: Option<f64>, period: usize, ) -> Self

Creates a new detector with seasonal awareness.

• lookback — rolling window size (default 100).
• k — number of standard deviations for the threshold (default 3.0).
• period — number of data points per seasonal cycle (e.g. 24 for hourly data with daily seasonality). When set, the detector computes per-bucket statistics (same position within each cycle) and compares new points against their matching bucket.

Trait Implementations

impl AnomalyDetector for DynamicThresholdDetector

fn fit( &mut self, _timestamps: &[i64], values: &[f64], ) -> Result<(), AnomalyError>

Fit the detector on historical data.

fn detect( &mut self, timestamps: &[i64], values: &[f64], ) -> Result<Vec<AnomalyScore>, AnomalyError>
