I have an option to do daily or weekly forecasting of cash deposits and withdrawals at the bank ATMs using the time series data over the past 5 years. Based on the text (https://otexts.com/fpp2/), it seems to me that harmonic dynamic regression using the Fourier terms and neural network are the most suitable options.
The demand for cash is highly correlated with the holidays (Labor Day, Christmas, Easter) some of which move from year to year. Is it something I need to worry about if I use the weekly forecasting or is it an issue mainly for daily (or day of the week) forecasting? Does the harmonic regression take care of it using the Fourier terms automatically?
Any advice is appreciated.
