Function ets

ets(
    y: ArrayLike<number | null | undefined>,
    options?: {
        alpha?: number;
        beta?: number;
        confidence?: number;
        gamma?: number;
        horizon?: number;
        method?: "ses" | "des" | "winters-add" | "winters-mul";
        seasonLength?: number;
    },
): EtsResult
Exponential smoothing: SES, Holt DES, or Holt–Winters (additive / multiplicative). Smoothing parameters are optimised by SSE grid search unless supplied. Forecast intervals use Hyndman approximations (σ from in-sample one-step SSE).
Parameters
- y: ArrayLike<number | null | undefined>
- Optionaloptions: {
      alpha?: number;
      beta?: number;
      confidence?: number;
      gamma?: number;
      horizon?: number;
      method?: "ses" | "des" | "winters-add" | "winters-mul";
      seasonLength?: number;
  }
Returns EtsResult
