The deviance information criterion (DIC) is a hierarchical modeling generalization of the Akaike information criterion (AIC). It is particularly useful in Bayesian model selection problems where the posterior distributions of the models have been obtained by Markov chain Monte Carlo (MCMC) simulation. DIC is … See more In the derivation of DIC, it is assumed that the specified parametric family of probability distributions that generate future observations encompasses the true model.

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.

WebMar 21, 2024 · By contrast, the widely used deviance information criterion (DIC), a different measure that balances model accuracy against complexity, is commonly considered a much faster alternative.
