The Residual Plot provides several features to investigate your data. These features
are available in both the scatter plot and histogram. The process to activate these
features is the same in either plot. The available features are plot the residuals
by a
category variable, show only the selected observations, exclude selected observations, and remove all
exclusions.
There are two ways to select observations in the Residual Plot. If you hold the mouse
over an individual point, you can click
on that point to select it. Alternatively, when you click and drag the mouse in the
Residual Plot, a selection rectangle appears. When you release the mouse, all points
inside the rectangle are selected.
To plot the residuals by a category variable, right-click in the Residual Plot, select
Plot
By, and then select a category variable. A
box plot of the residuals appears. The residuals are grouped by the selected category variable.
To show selected observations, select some
data points, right-click in the Residual Plot, and select
Show
Selected. A table of the selected observations appears.
To exclude selected observations, select some data points, right-click in the Residual
Plot, and select Exclude Selected. The selected
observations are no longer used to build the model.
To remove all exclusions,
right-click anywhere in the Residual Plot, and select Remove
Exclusions. All observations are now used to build in the model.
