Web6 de mai. de 2024 · I have been reading a couple related papers using Bayesian inference in hierarchical models 1, 2, 3 but am struggling to bridge the gap in one aspect of the papers. I think the struggle is in relation to the posterior predictive distribution. Bayesian hierarchical modelling is a statistical model written in multiple levels (hierarchical form) that estimates the parameters of the posterior distribution using the Bayesian method. The sub-models combine to form the hierarchical model, and Bayes' theorem is used to integrate them with the observed data and account for all the uncertainty that is present. The result of this integration is the posterior distribution, also known as the updated probability estimate, as additional eviden…

WebA hierarchical model is a particular multilevel model where parameters are nested within one another. Some multilevel structures are not hierarchical – e.g. “country” and “year” are not nested, but may represent separate, but overlapping, clusters of parameters. We will motivate this topic using an environmental epidemiology example.
