Exercise

A comprehensive time series diagnostic

Each plotting function that you've learned so far provides a different piece of insight about a time series. By putting together the histogram, the box and whisker plot, the autocorrelogram, and the q-q plot, you can gather a lot of useful information about time series behavior.

In this exercise, you will explore the ExxonMobil return data in the rtn series available in your workspace.
