WebOne rewrites the hyperprior distribution in terms of the new parameters μ and η as follows: μ, η ∼ π(μ, η), where a = μη and b = (1 − μ)η. These expressions are useful in writing the JAGS script for the hierarchical Beta-Binomial Bayesian model. A hyperprior is constructed from the (μ, η) representation.
