template<typename T_shape , typename T_scale , class RNG >

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

inline

Return a pseudorandom inverse gamma variate for the given shape and scale parameters using the specified 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_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)
beta	(Sequence of) positive scale parameter(s)
rng	random number generator

Returns

(Sequence of) inverse gamma random variate(s)

Exceptions

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