With `seasonality_mode='multiplicative'`, holiday effects will also be modeled a s multiplicative. Any added seasonalities or extra regressors will by default us e whatever `seasonality_mode` is set to, but can be overriden by specifying `mod e='additive'` or `mode='multiplicative'` as an argument when adding the seasonal ity or regressor. | With `seasonality_mode='multiplicative'`, holiday effects will also be modeled a s multiplicative.
