SUBMIT YOUR IDEAGreat challenge for learning about batch macros and time series tools! Sadly, the interactive chart tool kept crashing for me, so I wasn't able to render all the charts, however, I was able to get a screenshot from within the interactive chart tool.
Macro:
Example output graph:
A hard one, for sure. Get a chance to look at TS Model Factory and TS Forecast Factory. the R code looks insane on the inside but the output columns are very useful. It would definitelybe a great experience knock on those code.
Could build a macro myself by looping the ARIMA model tool and forecast tool.
Tried.
Well that was fun - learnt lots there. Great opportunity to practice the batch macro - obviously it could be avoided but I feel like you have to use the batch macro to have really completed this challenge.
I think there is an issue with ETS (at the time of writing), but ARIMA gives sensible results, so I went with that. I believe most people who have really looked at the forecast have hit the same issue with ETS. I have posted a comment on the Discussion forum under the thread "Impossible to get results with the ETS tool" for anyone who wants to really get into the detail. If anyone has got plausible forecasts from ETS for this challenge I would love to hear.
I would like to say I enjoyed this one, but I kept struggling with some of the R Tools 'not initializing.' Quite frustrating. Regardless, finally got it. Not much different than others.
