Comparison of model evidence for each simulated dataset and model.

This was computed with sequential Monte Carlo (SMC), using the integrated likelihood and separately using the full likelihood. This was repeated for 8 random initialisations with 2000 draws at each step in SMC, and we present the mean and standard deviation of the model evidence from each run. For each approach, the model with the strongest evidence is marked with * (this is not clear for with rounding here, but see the repository [17] for full results). For each model, we also report the time taken to complete the sampling for all initialisations, averaged across the different datasets.
