### DIC to compare models with different numbers of parameter?

I am interested in comparing hierarchical Bayesian models based on the same dataset but differing in their spatial and temporal resolution. In short, I am looking at animal population changes over ...

### Calculating DIC from MCMC (gibbs) output

I just want to make sure my understanding of how we estimate DIC using MCMC output is correct, as the wikipedia page is somewhat confusing. Defining DIC by $$DIC = p_D + \bar{D}$$ with D(\theta) ...

### DIC, WAIC in JAGS

I have a Bayesian Hierarchical model using JAGS. In order to find the best model, I have compared the DIC of two models but It's not reliable. So, I decided to calculate WAIC from JAGS. However I have ...

### DIC model selection: preferred model does not contain significant term

I estimate model parameters for 2 glmm models using MCMC in R2JAGS. I then use DIC to assess the relative fit of the models: Model 1 y~ site + treatment (DIC = 922.1) Model 2 y~ site (DIC = 921.8) ...
Imagine I have the following 7 glmm models where $b_1$ through $b_3$ are fixed effects. $M_1 = y \sim b_1 \times b_2 \times b_3$ $M_2 = y \sim b_2 \times b_3$ $M_3 = y \sim b_1 \times b_3$ \$M_4 = ...
