Struct HoltLinear 

pub struct HoltLinear { /* private fields */ }

Holt’s Linear Exponential Smoothing.

Implementations

impl HoltLinear

pub fn new(alpha: f64, beta: f64) -> Option<Self>

Creates a new Holt smoother.

Parameters

• alpha: level smoothing constant ∈ (0, 1)
• beta: trend smoothing constant ∈ (0, 1)

Returns None if parameters are out of range.

pub fn alpha(&self) -> f64

Returns α.

pub fn beta(&self) -> f64

Returns β.

pub fn smooth(&self, data: &[f64]) -> Option<HoltResult>

Applies Holt’s linear smoothing to the data.

Requires at least 2 data points. Returns None if data has fewer than 2 points.
