You can use the Plots tab to create plots that graphically display results of the analysis. (See Figure 21.15.) 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 partial leverage plot for each regressor and for the intercept. A line in the plot has a slope equal to the parameter
estimate in the full model. Confidence limits for each regressor are related to the confidence limits for parameter estimates.
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 studentized residuals versus the predicted value.
creates a scatter plot of the studentized residuals versus the leverage statistic.
creates a scatter plot of Cook’s D statistic
for each observation.
creates a scatter plot of the leverage statistic for each observation.
creates a scatter plot of the PRESS residual
for each observation.
creates a scatter plot of the covariance ratio
for each observation.
creates a scatter plot of the DFFIT statistic
for each observation.
