I am trying to use the TS Covariate Forecast tool to forecast sales for 31 days in Jan 2023.
The inputs to the TS Covariate Forecast tool are the Output stream from the ARIMA tool and a dataset that has the dates and covariates for each day in Jan 2023.
I am getting the following error:
Error: TS Covariate Forecast (53): TS Forecast: Error in `contrasts<-`(`*tmp*`, value = contr.funs[1 + isOF[nn]]) :
I am using 10 years of data until 2022 to train the ARIMA model.
Is there an example that I could use to understand how to do this?
