Challenge #24: ARIMA Time Series

Highlighted

After struggling to figure out what I was doing wrong as I couldn't match the output, I finally looked at some other posts and see that others have the same issue.

Here we go. Had to take a sneak at the official solution to check time series output (which doesn't seem to match the output data).

Challenge #24, done.

 

This one was left behind because I had to recap ARIMA and ETS models before doing it. 

Although it was pretty straight forward the approach on this challenge, it's good to know you're not doing anything wrong.

PS: I did not use a single summarize tool in here. I created Imputation batch macros to replace Null Values. It's always nice to have a different idea on how to solve a problem.
