“…Rather than the optimal fit, the marginal likelihood measures a model's average fit. Unfortunately, more than a decade after its introduction in psychology (but see Edwards, Lindman, & Savage, 1963, for an early example), there are only a handful of studies relying on the marginal likelihood for model evaluation (e.g., Lee, 2004;Massaro, Cohen, Campbell, & Rod riguez, 2001;Navarro & Lee, 2003;Steyvers, Lee, & Wagenmakers, 2009). Furthermore, we know of no study that has used the marginal likelihood to evaluate prototype and exemplar models against empirical data, let alone the intermediate models in the broader VAM family.…”
