WebAug 5, 2016 · The deviance information criterion (DIC) was introduced in 2002 by Spiegelhalter et al. to compare the relative fit of a set of Bayesian hierarchical models. It is similar to Akaike's information criterion (AIC) in combining a measure of goodness-of-fit and measure of complexity, both based on the deviance. While AIC uses the maximum … WebMar 26, 2024 · The Akaike information criterion (AIC) is a mathematical method for evaluating how well a model fits the data it was generated from. In statistics, AIC is used to compare different possible models and determine which one is the best fit for the data. AIC is calculated from: the number of independent variables used to build the model.

WebDIC is a Bayesian version of AIC. Like AIC, it trades o a measure of model adequacy against a measure of complexity and is concerned with how replicate data predict the observed data. Unlike AIC, DIC takes prior information into account.
