Table 3. Model and prior fits.
a) The winning model is that with the lowest Leave-One-Out Information Criterion (LOOIC). The lowest two numbers (for bandit4arm_lapse and bandit4arm_lapse_decay) are displayed in bold. b) The lowest LOOIC is then obtained when the top two models are fit with two priors: one for symptomatic and one for healthy individuals (Diagnosis priors). † Note that fitting the decay model with a single prior did not converge rendering the LOOIC value meaningless.
