Hi Mark, thanks for using our package! Yes, for short horizons the benefits of NHITS over NBEATSx diminish. For a forecasting horizon of 7 I suggest using the NBEATSx first.

Awesome, thanks for developing the package and the quick reply! If I could ask a follow up, in order to capture the yearly seasonality, would you recommend using a long n_time_in (365) or including a representation of the day of year as another exogenous variable? (I was thinking that the latter would work better)

no problem! yes, I suggest adding the day of year as an exogenous variable

Great, appreciate the answers here
