Comparison of probabilistic choice models in humans

Table 1 Parameters and AICc (Akaike Information Criterion with small sample correction) of probabilistic choice models for group data

	Entropy model		Prelec's function		General hyperbola		Simple hyperbola
AICc	137.96		138.61		139.46		143.05
Parameter	a	T	α	β	k	s	k
	0.59437	0.21222	0.75456	1.02024	3.21403	0.55207	1.195

For group median data (N = 21) for each indifference point, goodness of fitting was [Entropy model>Prelec's function>General hyperbola>Simple hyperbola]. Note that smaller AIC (Akaike Information Criterion) corresponds to better fitting to behavioral data. It was confirmed that β ≈ 1, and s < 1 for group data.
