The column labeled RSS reports the average of the residual sum of squares across participants. LL indicates the average of the log-likelihood across participant. AIC was computed per participant using Equation 7, and the average is reported here. R2 is the squared correlation coefficient between true and predicted response. NAN = not a number.
