VectorBuilder< true, double, T_shape1, T_shape2 >::type stan::math::beta_rng	(	const T_shape1 &	alpha,
		const T_shape2 &	beta,
		RNG &	rng
	)

inline

Return a Beta random variate with the supplied success and failure parameters using the given random number generator.

alpha and beta can each be a scalar or a one-dimensional container. Any non-scalar inputs must be the same size.

Template Parameters

T_shape1	type of success parameter
T_shape2	type of failure parameter
RNG	type of random number generator

Parameters

alpha	(Sequence of) positive finite success parameter(s)
beta	(Sequence of) positive finite failure parameter(s)
rng	random number generator

Exceptions

std::domain_error	if alpha or beta are nonpositive
std::invalid_argument	if non-scalar arguments are of different sizes
