Mar 15,  · Mapping multiple quantitative trait loci (QTL) is commonly viewed as a problem of model selection. Various model selection criteria have been proposed, primarily in the non-Bayesian framework. The deviance information criterion (DIC) is the most popular criterion for Bayesian model selection and Cited by: 7. DIC: Deviance Information Criteria DIC (Deviance Information Criterion) is a Bayesian method for model comparison that WinBUGS can calculate for many models. Full details of DIC can be found in Spiegelhalter DJ, Best NG, Carlin BP and Van der Linde A, “Bayesian Measures of Model Complexity and Fit (with Discussion)”, Journal of the Royal Statistical [ ]. Thus pD is the posterior mean of the deviance minus the deviance of the posterior means. DIC. The Deviance Information Criterion is given by DIC = Dbar + pD = Dhat + 2 * pD. The model with the smallest DIC is estimated to be the model that would best predict a replicate dataset of the same structure as that currently observed.

DIC (Deviance Information Criterion) is a Bayesian method for model How does the pD in WInBUGS compare to the pV in Andrew Gelman's bugs. In WinBUGS the quantity deviance is automatically calculated, where θ Deviance Information Criterion, DIC = 'goodness of fit' + 'complexity'. The deviance information criterion (DIC) introduced by Spiegelhalter et al. .. easily handled by winBUGS , the use of DIC for these models is not possible in.

Abstract: The deviance information criterion (DIC) was introduced in by Spiegel- and its implementation in the Bayesian software package WinBUGS[3 ]. Calculation of deviance information criterion Multiple chains Other tools and menus Monitoring the acceptance rate of the Metropolis-Hastings algorithm Saving the current state of the chain Setting the starting seed number Running the model as a script Summary and concluding remarks. Thus pD is the posterior mean of the deviance minus the deviance of the posterior means. DIC. The Deviance Information Criterion is given by DIC = Dbar + pD = Dhat + 2 * pD. The model with the smallest DIC is estimated to be the model that would best predict a replicate dataset of the same structure as that currently observed. 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 an asymptotic approximation as the sample size becomes large, like AIC. Mar 15,  · Mapping multiple quantitative trait loci (QTL) is commonly viewed as a problem of model selection. Various model selection criteria have been proposed, primarily in the non-Bayesian framework. The deviance information criterion (DIC) is the most popular criterion for Bayesian model selection and Cited by: 7. • Natural way to compare models is to use criterion based on trade-off between the fit of the data to the model and the corresponding complexity of the model • Spiegelhalter et al () proposed a Bayesian model comparison criterion based on this principle: Deviance Information Criterion, DIC = ‘goodness of fit’ + ‘complexity’. DIC: Deviance Information Criteria DIC (Deviance Information Criterion) is a Bayesian method for model comparison that WinBUGS can calculate for many models.

Using DIC to compare selection models with non-ignorable missing responses the data at hand. For complete data, the Deviance Information Criterion (DIC) is routinely used for Bayesian model comparison. However, when an analysis includes missing data, DIC can be facilitated by its automatic calculation by the WinBUGS software, which. Deviance Information Criterion (DIC) The DIC is a widely used GOF statistic for comparing models in a Bayesian framework (Spiegelhalter et al. ). DIC is a hierarchical modeling generalization of the Akaike Information Criterion (AIC) and Bayesian Information Criterion (BIC), defined as: DIC D() PD .
