Struct ChangePointDetection 

pub struct ChangePointDetection { /* private fields */ }

Change point detection kernel.

Detects points in a time series where statistical properties change. Supports PELT, Binary Segmentation, and CUSUM methods.

Implementations

impl ChangePointDetection

pub fn new() -> Self

Create a new change point detection kernel.

pub fn compute( series: &TimeSeries, method: ChangePointMethod, penalty: f64, min_segment: usize, ) -> ChangePointResult

Detect change points in a time series.

Arguments

• series - Input time series
• method - Detection method
• penalty - Penalty for adding change points (higher = fewer points)
• min_segment - Minimum segment length
