draw8Dirichlet: simulates random draws from a Dirichlet

In rebastaba: Handling Bayesian networks

Description

(dn) No more than a copy of rdirichlet found in mc2d package adapted for our parameterization. The A vector of values is the sum of usual A_i; The a vector of vectors (then a matrix) is the proportions associated to the usual A_i.

Usage

draw8Dirichlet(n, A, a)

Arguments

n	Number of draws to obtain.
A	Vector [n] of the confidences given to each Dirichlet.
a	Matrix [n,k] of the proportions for each one.

Value

a matrix [n,k] of the draws is returned

Examples

 set.seed(1234);draw8Dirichlet(5, 1:5, matrix(1:15, 5));
 set.seed(1234);draw8Dirichlet(5, rep(1, 5), matrix(1:15, 5));
