Model comparison based on the LOO criterion. The best-ranked model has a ∆LOO of zero. The x-axis shows the difference in the LOO for the models considered in each visit (y-axis). The error bars represent the standard error of the difference in the expected log-predictive density between each model and the top-ranked model. By definition, the standard error of the top-ranked model is zero. In visit 1, the ∆LOO to the second-ranked model is above 50 and thus is not visible in the plot. The red diamond represents a sinusoidal phase curve, the green cross is the piecewise-Lambertian model, the cyan hexagon is the Lambertian sphere, the orange star is a flat baseline without an eclipse, and the violet circle is a flat baseline with the eclipse as a free parameter.
