## Example of valid Dirichlet mixture parameter for tri-variate extremes.

### Description

The Dirichlet mixture density has three components, the center of mass of the three columns of `Mu`

, with weights `wei`

is *(1/3,1/3,1/3)*: the centroid of the two dimensional unit simplex.

### Format

A list made of

- Mu
A *3*3* matrix, which rows sum to one, such that the
center of mass of the three column vectors (weighted with `wei`

) is the centroid of the simplex: each column is the center of a Dirichlet mixture component.

- wei
A vector of length three, summing to one: the mixture weights

- lnu
A vector of length three: the logarithm of the concentration parameters.
