    pub gamma: f64,
    pub phi: f64,
}

Expand description

The parameters of an ETS model.

Fields§

§alpha: f64

The value of the smoothing parameter for the level.

If alpha = 0, the level will not change over time. Conversely, if alpha = 1 the level will update similarly to a random walk process.

§beta: f64

The value of the smoothing parameter for the slope.

If beta = 0, the slope will not change over time. Conversely, if beta = 1 the slope will have no memory of past slopes.

§gamma: f64

The value of the smoothing parameter for the seasonal pattern. If gamma = 0, the seasonal pattern will not change over time. Conversely, if gamma = 1 the seasonality will have no memory of past seasonal periods.

§phi: f64

The value of the dampening parameter for the slope. If phi = 0, the slope will be dampened immediately (no slope). Conversely, if phi = 1 the slope will not be dampened.
