WitrynaSee[BAYES] Bayesian estimation. Inference is the next step of Bayesian analysis. If MCMC sampling is used for approximating the posterior distribution, the convergence of MCMC must be established before proceeding to inference (see, for example,[BAYES] bayesgraph and[BAYES] bayesstats grubin). Point and interval estimators MCMC … WitrynaImportance sampling is a Bayesian estimation technique which estimates a parameter by drawing from a specified importance function rather than a posterior distribution. Importance sampling is useful when the area we are interested in may lie in a region that has a small probability of occurrence.

The exercise of point estimation is to use particular functions of the data in order to estimate certain unknown population parameters.
