Density function and random generation for the multivariate Student-t
distribution with location vector `mu`

, covariance matrix `Sigma`

,
and degrees of freedom `df`

.

```
dmulti_student_t(x, df, mu, Sigma, log = FALSE, check = FALSE)
rmulti_student_t(n, df, mu, Sigma, check = FALSE)
```

- x
Vector or matrix of quantiles. If

`x`

is a matrix, each row is taken to be a quantile.- df
Vector of degrees of freedom.

- mu
Location vector with length equal to the number of dimensions.

- Sigma
Covariance matrix.

- log
Logical; If

`TRUE`

, values are returned on the log scale.- check
Logical; Indicates whether several input checks should be performed. Defaults to

`FALSE`

to improve efficiency.- n
Number of draws to sample from the distribution.
