# Density of multivariate t-distribution

In this exercise, you will calculate the density of multivariate t-distributions using the 200 samples generated in the previous exercise, that were stored in the `multt.sample`

object.

Instructions

**100 XP**

- Calculate the density heights of the 200 samples in
`multt.sample`

for a bivariate t-distribution with location`mu.sim`

, variance-covariance matrix`sigma.sim`

and 5 degrees of freedom. - Create a 3d scatterplot to visualize the density heights at each of the 200 points.
