Challenge #24: ARIMA Time Series

First time working with ARIMA. Pretty easy but doesn't seem to take seasonality into account.

My Solution

Hi All , 

For the forecast Still, I need to understand what sort of forecasting you need the challenge is it weekly or monthly or annually basis?

My solution.  At first my results at each confidence interval were different than the provided solution, but after I bounced around with different field types (double, to float, to int64, and back to double), they matched exactly.  Weird.
