Hierarchical Bayesian inference for concurrent model fitting and comparison for group studies

Robustness of model selection to outliers.
The same 20 datasets simulated in the previous section were used as the base datasets (i.e. 0 outliers) and the effects of adding 1, 2 or 3 outliers to each dataset were examined. The HPE shows severe sensitivity to outliers, while the other two (random effects) methods are robust.
