aesara.tensor.random.dirichlet = <aesara.tensor.random.basic.DirichletRV object>[source]#

A Dirichlet continuous random variable.

The probability density function for dirichlet in terms of the vector of concentration parameters $\boldsymbol{\alpha}$ is:

$f(x; \boldsymbol{\alpha}) = \prod_{i=1}^k x_i^{\alpha_i-1}$

where $x$ is a vector, such that $x_i > 0\;\forall i$ and $\sum_{i=1}^k x_i = 1$ .
