Struct StlConfig 

pub struct StlConfig {
    pub period: usize,
    pub n_iter: usize,
    pub trend_window: Option<usize>,
    pub seasonal_window: Option<usize>,
}

Configuration for the STL decomposer.

Fields

period: usize

Seasonal period (e.g., 24 for hourly data with daily seasonality).

n_iter: usize

Number of outer-loop iterations (default: 2).

trend_window: Option<usize>

Trend smoother window length — must be odd, ≥ 3. Default: period + 1 (rounded up to next odd).

seasonal_window: Option<usize>

Seasonal subseries smoother window length — must be odd, ≥ 3. Default: max(7, period) (rounded up to next odd). R’s STL defaults to at least 7; the previous hardcoded value of 3 was too small and allowed noise into the seasonal component.

Implementations

impl StlConfig

pub fn new(period: usize) -> Self

Creates a new STL configuration with the given seasonal period.

pub fn with_iterations(self, n: usize) -> Self

Sets the number of STL iterations.

pub fn with_trend_window(self, w: usize) -> Self

Sets the trend smoother window length.

pub fn with_seasonal_window(self, w: usize) -> Self

Sets the seasonal subseries smoother window length.
