VectorBuilder< true, double, T_deg, T_scale >::type stan::math::scaled_inv_chi_square_rng	(	const T_deg &	nu,
		const T_scale &	s,
		RNG &	rng
	)

inline

Return a scaled chi square random variate for the given number of degrees of freedom and scale using the specified random number generator.

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

Template Parameters

T_deg	type of degrees of freedom parameter
T_scale	type of scale parameter
RNG	type of random number generator

Parameters

nu	(Sequence of) positive degrees of freedom parameter(s)
s	(Sequence of) positive scale parameter(s)
rng	random number generator

Exceptions

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