WebThis Primer describes the stages involved in Bayesian analysis, from specifying the prior and data models to deriving inference, model checking and refinement. We discuss the importance of prior and posterior predictive checking, selecting a proper technique for sampling from a posterior distribution, variational inference and variable selection. http://odin.mdacc.tmc.edu/~jmorris/talks_files/mcmc2.pdf
