◆ frechet_rng()

template<typename T_shape , typename T_scale , class RNG >

VectorBuilder< true, double, T_shape, T_scale >::type stan::math::frechet_rng	(	const T_shape &	alpha,
		const T_scale &	sigma,
		RNG &	rng
	)

inline

Return a pseudorandom Frechet variate for the given shape and scale parameters using the specified random number generator.

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

Template Parameters

T_shape	type of shape parameter
T_scale	type of scale parameter
RNG	type of random number generator

Parameters

alpha	(Sequence of) positive shape parameter(s)
sigma	(Sequence of) positive scale parameter(s)
rng	random number generator

Exceptions

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