Posterior probability densities (Inference->Samples->density)

(Further, right-click on the figure->Margins-> Special…->Smooth -> change from 0.2 to 0.1-> apply all)

Sample autocorrelation function (Inference->Samples->auto corr)

Running quantile plot (Inference->Samples->quantiles)

Scatter plots (Inference->Correlations…)

Posterior predictive analysis. pleft:Pr(ypred[i] =< y[i]). pright: Pr(y.pred[i]>=y[i])
