Results of Bayesian model selection (BMS). A, Pooled log-evidences of the 12 DCMs tested. It can be seen that the best model is l-ILEN (log-evidence = −24,297) and the next best is b-ILEN (log-evidence = −25,880). B, Comparison of the average log-evidences for the three purely linear (ILEL) models and the remaining nonlinear models; shown for each subject. The positive slopes over all subjects indicate that the nonlinear coupling is essential as the nonlinear models are always better than the linear ones. C, BMS on partitioned model space reveals that the ILEN model is the best model.
