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

Table 17.8: 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 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
