Figure 2

Scatterplots of individual parameter values of each probabilistic choice model (horizontal axis): (a) parameters of entropy model, (b) parameters of Prelec's weight functions, (c) parameters of general hyperbolic function, and (d) a parameter of simple hyperbolic function) and AUC (Area Under the Curve, vertical axis). Note that small AUC indicates subject's strong aversion to possible non-gain in each probabilistic choice (risk aversion). Note that a of entropy model, β of Prelec's weight function, and s of general hyperbolic function, and k of simple hyperbolic function were significantly negatively correlated with AUC, while other parameters such as T in the entropy model (an indicator of aversion to unpredictability) were not significantly correlated with AUC.
