The hyper-parameter for the Gamma prior distribution (with mean = a/b) of the precision (inverse variance) model parameters (e.g., 1/\(\sigma\)2_\(\epsilon\), 1/\(\sigma\)2_\(\eta\)).
beta.prior
The hyper-parameter for the Normal prior distribution of the \(\beta\) model parameters.
rho.prior
The hyper-parameter for the Normal prior distribution of the \(\rho\) model parameter.
