WebJun 16, 2024 · The DIC refers to the Deviance Information Criterion. It is a combination of the deviance for a model and a penalty for the complexity of the model. The measure is defined and derived in a paper by Spiegelhalter et al. (2002). The DIC is only calculated for numeric data in AMOS. If you have checked the 'Allow non-numeric data' box in the Data ... WebDIC is similar to AIC, but its penalty term is based on a complexity term that measures the difference between the expected log likelihood and the log likelihood at the posterior mean point. DIC is designed specifically for Bayesian estimation that involves MCMC simulations.

The DIC is a more Bayesian alternative that uses the posterior mean point estimate instead of the maximum likelihood estimate. Here the posterior mean point estimate is nothing but the ... WebOct 9, 2024 · DIC is a more complex information criterion which has a more sophisicated means of finding the effective number of parameters. It uses a discriminative principle where the goal is to select the model less likely to have generated data belonging to the competing classification categories ( link ). cynthia brinson atlanta

For model comparison, the model with the lowest AIC score is preferred. The absolute values of the AIC scores do not matter. These scores can be negative or positive. billy regal 40 tief
