dm.expar.D3k3: Example of valid Dirichlet mixture parameter for tri-variate...

Description Format


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.


A list made of


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.


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


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