WebbThe modelCalibrationPlot 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. By default, predicted EAD values are plotted in the x -axis, but predicted EAD values ... WebbA residual plot shows the fitted values of the response variable on the x-axis and the studentized or standardized residuals on the y-axis. It can be used to check for correlated residuals or non-constant variance of the residuals, both of which would violate the residual assumptions of a linear model.
