is there any news regarding implements of Seasonal Arima ? Or it can be done by just porting R scripts ? I'm looking to do something like this in R, using the forecast package:
Arima(ts, order = c(1,0,3), seasonal = c(2,1,0))
I know there is a Seasonality Correction node, but I'm not sure if this would help. Please let me know if you need more information about my intended implementation.
