inline

The log of an inverse gamma density for y with the specified shape and scale parameters.

Shape and scale parameters must be greater than 0. y must be greater than 0.

Parameters

y	A scalar variable.
alpha	Shape parameter.
beta	Scale parameter.

Exceptions

std::domain_error	if alpha is not greater than 0.
std::domain_error	if beta is not greater than 0.
std::domain_error	if y is not greater than 0.

Template Parameters

T_y	Type of scalar.
T_shape	Type of shape.
T_scale	Type of scale.
