You can use the Plots tab to create plots that graphically display results of the analysis. (See FigureĀ 22.4.) There are plots that help you to visualize the fit, the residuals, and various influence diagnostics.
Creating a plot often adds one or more variables to the data table. The following plots are available:
creates a scatter plot of the Y variables versus the predicted values, overlaid with the diagonal line that represents a perfect
fit.
creates a scatter plot of the residuals versus the predicted values.
creates scatter plots of the residuals versus the X variables.
creates a scatter plot of the internally studentized residuals versus the robust distance.
The robust distance is a measure of the distance between an observation and a robust estimate of location. The distance function
uses robust estimates of scale and location computed by the minimum covariance determinant (MCD) method.
creates a scatter plot of the robust distance versus the Mahalanobis distance.
