TS Forecast Factory

Hello All,

I am building a blended TS forecast with multiple Forecast tools, and I have ran into a problem with my Arima Forecast using the TS Forecast Factory. It says only 551 Groups are being entered but 554 are actually being entered. I have tried this a few different ways and keep coming up with an error showing a few groups less than I am sending in with covariates. Any help is appreciated.

Thanks,

Nick

So i haven't solved whats wrong with the three groups yet but apparently there is no covariate forecast being created. I started testing to narrow the codes and during that I found the warning will tell you which groups are not generating a covariate forecast. I then just needed to create an additional filter test to remove them (I used an additional MAPE filter), after the TS model factory which seems to have worked.

Thanks again for any time spent on this.

Could it be that you're feeding in duplicate values @Nick1 ?

Thanks for the suggestion, I ran the 554 through the unique tool to be sure and they are all unique, I have the groups summed earlier in the workflow that should remove that issue.

Thanks,

Nick
