Set computational options for the sampling algorithms used for a 'gen' model component
gen_control(MHprop = c("GiG", "LNRW"))
A list of computational options regarding a 'gen' model component.
MH proposal for the variance component in case of a MLiG prior
on the coefficients. The two options are "GiG" for a generalized inverse gamma
proposal, and "LNRW" for a log-normal random walk proposal. The former should
approximate the conditional posterior quite well provided MLiG parameter a
is large, such that the coefficients' prior is approximately normal.
