Bayes factor B^ABC_CI computed with different annealing schedules in population annealing and different last epsilons in ABC rejection sampler.

Abbreviations are as follows: PA: population annealing, ARS: ABC rejection sampler. AS1: annealing schedule 1 = (∞, 2, 1, 0.75, 0.5, 0.25), AS2: annealing schedule 2 = (∞, 1, 0.5, 0.25, 0.2, 0.15), AS3: annealing schedule 3 = (∞, 1, 0.5, 0.25, 0.15, 0.11).
