The ANOVA Procedure
Syntax: ANOVA Procedure
The following statements are available in the ANOVA procedure:
PROC ANOVA
<options> ;
CLASS
variables </ option> ;
MODEL
dependents = effects </ options> ;
ABSORB
variables ;
BY
variables ;
FREQ
variable ;
MANOVA
<test-options> </ detail-options> ;
MEANS
effects </ options> ;
REPEATED
factor-specification </ options> ;
TEST
<H=effects> E=effect ;
The PROC ANOVA, CLASS, and MODEL statements are required, and they must precede the first RUN statement. The CLASS statement must precede the MODEL statement. If you use the ABSORB, FREQ, or BY statement, it must precede the first RUN statement. The MANOVA, MEANS, REPEATED, and TEST statements must follow the MODEL statement, and they can be specified in any order. These four statements can also appear after the first RUN statement.
Table 25.1 summarizes the function of each statement (other than the PROC statement) in the ANOVA procedure:
