Struct augurs_seasons::PeriodogramDetector

pub struct PeriodogramDetector { /* private fields */ }

A season detector which uses a periodogram to identify seasonal periods.

The detector works by calculating a robust periodogram of the data using Welch’s method. The peaks in the periodogram represent likely seasonal periods in the data.

Implementations

impl Detector

pub fn builder() -> Builder

Create a new detector builder.

pub fn periodogram(&self, data: &[f64]) -> Periodogram

Calculate the periodogram of the data.

The periodogram is a frequency domain representation of the data, and is calculated using the Welch method.

The periodogram can then be used to identify peaks, which are returned as periods which correspond to likely seasonal periods in the data.
