Exercise

Fourth moment: Kurtosis

Finally, to calculate the fourth moment of a distribution, you can use the kurtosis() function from scipy.stats.

Note that this function actually returns the excess kurtosis, not the 4th moment itself. In order to calculate kurtosis, simply add 3 to the excess kurtosis returned by kurtosis().

clean_returns from the previous exercise is available in your workspace.
