MAXORDERS Subcommand (ANOVA command)

MAXORDERS suppresses the effects of various orders of interaction.

ALL. Examine all interaction effects up to and including the fifth order. This is the default.

n. Examine all interaction effects up to and including the nth order. For example, MAXORDERS=3 examines all interaction effects up to and including the third order. All higher-order interaction sums of squares are pooled into the error term.

NONE. Delete all interaction terms from the model. All interaction sums of squares are pooled into the error sum of squares. Only main and covariate effects appear in the ANOVA table.
