posteriorDiscard

A "BayesianBrick" object used to select a method.

further arguments passed to or from other methods.

Contrary to posterior(), posteriorDiscard() a generic function that will update the prior distribution of a "BayesianBrick" object by removing the information provided by the observation's sufficient statistics. i.e. for the model structure: 
 theta|gamma ~ H(gamma) 
 X|theta ~ F(theta) 
update gamma to gamma_posterior by removing the information of X from gamma

A class of frequently used Bayesian parametric and nonparametric model structures, as well as a set of tools for common analytical tasks. Structures include Gaussian and Normal-Inverse-Wishart conjugate structure, Gaussian and Normal-Inverse-Gamma conjugate structure, Categorical and Dirichlet conjugate structure, Dirichlet Process on positive integers, Dirichlet Process in general, Hierarchical Dirichlet Process ... Tasks include updating posteriors, calculating marginal likelihood, calculating posterior predictive densities, sampling from posterior predictive distributions, calculating "Maximum A Posteriori" (MAP) estimates ...
