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.

Instructions

**100 XP**

- Import
`kurtosis`

from`scipy.stats`

`clean_returns`

to calculate the`excess_kurtosis`

. - Derive the
`fourth_moment`

from`excess_kurtosis`
