Challenge #24: ARIMA Time Series

[H_a_n_g_C_h_e_n__x3]

Can't figure how I am off in the 10 thousandth....

High and lows were a few decimal points off but the forecast was the same so I'm going to go with it

I noticed the same differences as others in the solution file's output; however, when testing against the solution's TS Forecast output my results were the same. 

Used the test tool to check some of my work and will be incorporating that in more workflows going forward. Also, I got in some Reporting practice to compare with the TS Forecast R output anchor. 

Overall, very useful and look forward to learning more on the Time Series capabilities. These would be a good add-on to historical reporting workflows.

I had not used ARIMA forecast tools so I watched the interactive videos as I did the challenge.  Thank you....
