Effect of state on risk behavior: Representative agent in EUT approach.

The values of the fitted risk parameters (using maximum likelihood estimation) as a function of state for the representative agent for all reward types. Note that the Constant variable represents the value in the deprived state and the State variable represents the addition (subtraction) during the satiated state. A BoldItalic font represents a significant effect of state. Alpha – the fitted risk parameter. Beta – the slope of the logit function. Coef. – the regression coefficient; Std Err – standard errors; z – z score of the regression; P>z – pvalue of the regression; CI – confidence interval.本数据集涵盖所有奖赏类型下，以状态为自变量的代表性主体（representative agent）拟合风险参数取值，拟合过程采用极大似然估计（maximum likelihood estimation）完成。需注意：常数项变量代表匮乏状态下的参数取值，状态变量则代表饱足状态下的增减量。粗斜体字体表示状态效应具有统计学显著性。Alpha为拟合风险参数；Beta为logit函数（logit function）的斜率；Coef.为回归系数；Std Err为标准误；z为回归的z分数；P>z为回归的p值；CI为置信区间。
