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. WebOct 29, 2010 · A Bayesian approach is considered to estimate the number of basis functions and the smoothing parameter of the hybrid splines non-parametric regression procedure. The method used to obtain the estimate of the regression curve and its Bayesian confidence intervals is based on the reversible jump MCMC (Green 1995).
