Detailed Description

Product of Beta distributions.

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

\[ f(x|\alpha,\beta) = \frac{\Gamma(\alpha+\beta)}{\Gamma(\alpha)\Gamma(\beta)}\, x^{\alpha-1}(1-x)^{\beta-1} \]

is a simplification of Dirichlet to univariate case.

void bdm::eBeta::from_setting ( const Setting &  set  )  [inline, virtual]

Create object from the following structure

    class = 'eBeta';
    alpha = [...];           % vector parameter alpha
    beta  = [...];           % vector parameter beta of the same length as alpha
