Webposterior mean or mode. Then, the deviance information criterion is defined as DIC = D(θ)+pD. The posterior mean deviance can be used as a Bayesian measure of model fit or ade-quacy. Hence, the deviance information criterion, which is the sum of the posterior mean deviance and the effective number of parameters, can be viewed as a trade ... WebVisualization of the deviance difference. Akaike Information Criterion (AIC) In many practical situations, the deviance provides an adequate criterion to discriminate models from one another. However, if we wish to estimate the best model with the least complexity, the deviance is not that useful because it tends to favor the most complex models. WebNext up is the Deviance Information Criterion or the DIC. The DIC is a more Bayesian alternative that uses the posterior mean point estimate instead of the maximum likelihood estimate.

WebJan 18, 2024 · Jan 18, 2024. Deviation information criteria (DIC) is a metric used to compare Bayesian models. It is closely related to the Akaike information criteria (AIC) which is defined as 2k −2ln ^L 2 k − 2 ln L ^, where k is the number of parameters in a model and ^L L ^ is the maximised log-likelihood. The DIC makes some changes to this formula.
