Webinvgamma is a special case of gengamma with c=-1, and it is a different parameterization of the scaled inverse chi-squared distribution. Specifically, if the scaled inverse chi-squared distribution is parameterized with degrees of freedom ν and scaling parameter τ 2, then it can be modeled using invgamma with a= ν / 2 and scale= ν τ 2 / 2.
