Simple Exponential Smoothing.

Implementations§

Source§

impl SimpleExponentialSmoothing

Source

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

Creates a new SES smoother.

§Parameters
  • alpha: smoothing constant, must be in (0, 1)

Returns None if alpha is out of range or non-finite.

Source

pub fn alpha(&self) -> f64

Returns the smoothing constant α.

Source

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

Applies SES to the given data.

Returns None if data is empty.
