I am running following data set:
PROC arima data= actuals_1c;
identify var=wrty_ut_sum nlag=8;
by product_line;
run;
estimate P=1 Q=1; RUN;
Forecast out= forecast_ARIMA(rename=(forecast=forecast_arima))
lead=78 id=date interval=week.7 ; run;
quit;
Then the estimation is not done and I get the ERROR: Forecasting was not performed because estimation was not done.
I am pretty sure is due to the BY statement on the PROC Arima, however I have tried different ways to fix it but I am not successful. I need the BY due to after this I am working with groups.
Any help or idea would be great :smileygrin:
