Comparison of probabilistic choice models in humans

Table 2 AICc (Akaike Information Criterion with small sample correction) and parameters of probabilistic choice models for individual data

	Entropy model		Prelec's function		General hyperbola		Simple hyperbola
AIC_c	133.31 ± 1.79		129.38 ± 1.80		130.82 ± 1.80		139.91 ± 1.80
Parameter	a	T	α	β	k	s	k
	0.691 ± 0.090	0.197 ± 0.045	0.774 ± 0.068	1.063 ± 0.075	10.910 ± 3.23	0.6348 ± 0.110	1.59 ± 0.33

All values are expressed as mean ± SEM. Note that β ≈ 1, and s < 1 for averaged values, and Prelec's model significantly better fit individual data than Simple hyperbola (p < 0.01, N = 20)
