Model Comparison

Model comparison can be achieved in much the same way we do with standard models

WAIC = widely applicable information criterion

• a Bayesian AIC (lower is better)

In the Bayesian context, we would have a distribution for the WAIC also

waic(attendance_brms, attendance_brms_add_re)

                                            WAIC     SE
attendance_brms                          2669.26 146.95
attendance_brms_add_re                   1420.24  26.20
attendance_brms - attendance_brms_add_re 1249.02 135.66
