Fitting an ARIMA model

In this exercise you'll learn how to be lazy in time series modeling. Instead of taking the difference, modeling the difference and then integrating, you're just going to lets statsmodels do the hard work for you.

You'll repeat the same exercise that you did before, of forecasting the absolute values of the Amazon stocks dataset, but this time with an ARIMA model.

A subset of the stocks dataset is available in your environment as amazon and so is the ARIMA model class.
