Model 1 - relative errors in the model predictions. Figure6.a plots the values of the measured vs. predicted states of the model. Note that the plot range is from 10−5to 10−4; 10 of the 1150 points have values less than 10−6and are not shown. Figure6.b shows an histogram of the residuals, which are calculated as, where the predicted values are. In both figures the results are plotted in a logarithmic scale.
