WebCross-validation with the different models will show the superiority of the hierarchical modeling approach. Cross-validation can be performed at 2 levels: Hold out students within a group and evaluate against its prediction. Hold out an entire group and evaluate its prediction. Note that this is not possible with the pooling model. 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. the primary english teacher\u0027s guide pdf
