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 73.4 describes the available plot-types and their plot-definition-options.

Table 73.4: Plot-Types and Plot-Definition-Options

Plot-Type and Description	Plot-Definition-Options
BOX
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
Displays a contour plot of predicted values against two continuous covariates	PLOTBY= variable or CLASS effect X= continuous variable Y= continuous variable
FIT
Displays a curve of predicted values versus a continuous variable	PLOTBY= variable or CLASS effect X= continuous variable
INTERACTION
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
MOSAIC
Displays a mosaic plot of predicted values by using up to three CLASS effects	PLOTBY= variable or CLASS effect X= CLASS effects
SLICEFIT
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
