This helped take the trepidation out of the ARIMA tool for me! Super fun!

Still clearing out solutions that I started but never finished a long time ago. Playing with ARIMA tools instead of writing out R code is much easier AND more dynamic (:

The output inside the comment box for the exercise doesn't match the output from the workflow of the solution file.

I tried a few manually configured ARIMA models to compare against the Auto model.  I found a manually configured (011)(011) model to be a better fit based on MASE (lower is better) vs the Auto generated model.  However, the exercise is looking for the auto-generated output.

Had a similar approach to the actual solution.

Not sure why the answer is slightly off from the provided answer, but it seems to be that way in the solution file as well. Mine matches that.

Here's my solution to challenge 24. 
Had to look up the tool required to actually interpret the model produced by the ARIMA tool.

Here's my solution! I don't know why my numbers are a little bit different...
