GammaScalePosterior
@Serializable
@SerialName(value = "GammaScalePosterior")
Gamma posterior over the scale of a Gamma likelihood with fixed shape - the shape is a posterior parameter rather than something we infer from data. Not an object because of that parameter.
GammaScalePosterior
fixedShape
Known shape parameter of the Gamma likelihood.
