SARIMA

ARIMA extended with seasonal components for periodic time series

SARIMA (Seasonal ARIMA) extends ARIMA with seasonal AR, differencing, and MA terms. It captures both trend-based and repeating seasonal patterns in univariate time series.

When to use:

  • Time series with clear seasonal patterns (weekly, monthly, yearly cycles)
  • Sales, energy consumption, weather, or web traffic data
  • Univariate forecasting with known seasonality period

Input:

  • Trained model checkpoint — exported SARIMA fit
  • Preprocessing config — scaling settings
  • Training tail — last N observations for lag features
  • Steps — forecast horizon in time steps

Output: Forecasted values for the specified horizon

Model Settings (set during training, used at inference)

AR Order (p) (default: 1) Non-seasonal autoregressive lag order.

Differencing (d) (default: 0) Non-seasonal differencing order.

MA Order (q) (default: 0) Non-seasonal moving average order.

Seasonal AR (P) (default: 1) Seasonal autoregressive order.

Seasonal Differencing (D) (default: 1) Seasonal differencing order.

Seasonal MA (Q) (default: 1) Seasonal moving average order.

Seasonal Period (m) (default: 12) Number of time steps per season (e.g., 12 for monthly data with yearly seasonality).

Inference Settings

No dedicated inference-time settings.
