Hello, I have an unusual time series:
The first time series has a seasonality of 24 and 168 (24x7). How would we specify this in Proc ARIMA ?
For instance if my assumed model is (1,1,2) X (1,1,2)24 X (2,2,1)168, how would I doe this in SAS proc arima ?
The second time series has a seasonality of 52 but within the 52 weekly we have 4 seasonal cycles (13 X 4 = 52), can you please let me know how I would specify these in Proc ARIMA ?
Thanks
