EFFECTPLOT Statement

EFFECTPLOT <plot-type <(plot-definition-options)>> </ options> ;

The EFFECTPLOT statement produces a display of the fitted model and provides options for changing and enhancing the displays. Table 66.2 describes the available plot-types and their plot-definition-options.

Table 66.2 *Plot-Types* and *Plot-Definition-Options*
Description	Plot-Definition-Options
BOX plot-type
Displays a box plot of continuous response data at each level of a CLASS effect, with predicted values superimposed and connected by a line. This is an alternative to the INTERACTION plot-type.	PLOTBY= variable or CLASS effect X= CLASS variable or effect
CONTOUR plot-type
Displays a contour plot of predicted values against two continuous covariates.	PLOTBY= variable or CLASS effect X= continuous variable Y= continuous variable
FIT plot-type
Displays a curve of predicted values versus a continuous variable.	PLOTBY= variable or CLASS effect X= continuous variable
INTERACTION plot-type
Displays a plot of predicted values (possibly with error bars) versus the levels of a CLASS effect. The predicted values are connected with lines and can be grouped by the levels of another CLASS effect.	PLOTBY= variable or CLASS effect SLICEBY= variable or CLASS effect X= CLASS variable or effect
SLICEFIT plot-type
Displays a curve of predicted values versus a continuous variable grouped by the levels of a CLASS effect.	PLOTBY= variable or CLASS effect SLICEBY= variable or CLASS effect X= continuous variable
