Dirichlet posterior density.

Continuous Dirichlet density of $n$ -dimensional variable $x$

$f(x|\beta) = \frac{\Gamma[\gamma]}{\prod_{i=1}^{n}\Gamma(\beta_i)} \prod_{i=1}^{n}x_i^{\beta_i-1}$

where $\gamma=\sum_i \beta_i$ .

void bdm::eDirich::from_setting ( const Setting & set ) [virtual]

Create object from the following structure

    class = 'eDirich';
    beta  = [...];           % vector parameter beta
