class statsmodels.tsa.holtwinters.Holt(endog, exponential=False, damped=False)[source]¶

Holt’s Exponential Smoothing wrapper(…)

Parameters:	endog (array-like) – Time series expoential (bool, optional) – Type of trend component. damped (bool, optional) – Should the trend component be damped.
Returns:	results
Return type:	Holt class

Notes

This is a full implementation of the holts exponential smoothing as per [1].
