Residual and Surface Plots

Residual plots provide visual displays for assessing how well the model fits the data, for evaluating the distribution of the residuals, and for identifying influential observations. Surface plots are three-dimensional displays of continuous response surfaces on the regular grids of the explanatory variables. They are much easier to comprehend than rotating plots.
