Bases: BaseStatsForecaster

Theta forecaster via statsforecast.

Standard Theta method for time series forecasting.

Parameters

Name	Type	Description	Default
season_length	int	Length of the seasonal period.	1
decomposition_type	str	Type of seasonal decomposition.	"multiplicative"
freq	str or None	Frequency string. Auto-inferred from data if None.	None
feature_transformer	BaseTransformer or None	Transformer applied to exogenous features before fitting/predicting.	None
target_transformer	BaseTransformer or None	Transformer applied to the target before fitting. Inverse-transformed after predicting to return forecasts in the original scale.	None
