Residual plot vs scatter plot
WebPurpose. These plots display the PWRES (population weighted residuals), the IWRES (individual weighted residuals), and the NPDEs (normalized prediction distribution errors) as scatter plots with respect to the time or the prediction. The PWRES and NPDEs are computed using the population parameters and the IWRES are computed using the … WebIf these scatterplots show a pattern, then the relationship may be nonlinear and the model will need to be modified accordingly. See Section 5.8 for a discussion of nonlinear regression. It is also necessary to plot the residuals against any predictors that are not in …
