WebbThis "residuals versus weight" plot can be used to determine whether we should add the predictor weight to the model that already contains the predictor age. In general, if there is some non-random pattern to the plot, it indicates that it may be worthwhile adding the predictor to the model. WebbThe modelAccuracyPlot function returns a scatter plot of observed vs. predicted loss given default (EAD) data with a linear fit and reports the R-square of the linear fit. The XData name-value pair argument allows you to change the x values on the plot.
