MANOVA: Univariate 845<br />

in the model. Parameters are estimated using DEVIATION contrasts to determine if their<br />

categories differ significantly from the mean.<br />

Subcommand Order<br />

• The variable list must be specified first.<br />

• Subcommands applicable to a specific design must be specified before that DESIGN subcommand.<br />

Otherwise, subcommands can be used in any order.<br />

<strong>Syntax</strong> Rules<br />

• For many analyses, the MANOVA variable list and the DESIGN subcommand are the only<br />

specifications needed. If a full factorial design is desired, DESIGN can be omitted.<br />

• All other subcommands apply only to designs that follow. If you do not enter a DESIGN subcommand<br />

or if the last subcommand is not DESIGN, MANOVA will use a full factorial model.<br />

• Unless replaced, MANOVA subcommands other than DESIGN remain in effect for all<br />

subsequent models.<br />

• MISSING can be specified only once.<br />

• The following words are reserved as keywords or internal commands in the MANOVA<br />

procedure: AGAINST, CONSPLUS, CONSTANT, CONTIN, MUPLUS, MWITHIN, POOL, R,<br />

RESIDUAL, RW, VERSUS, VS, W, WITHIN, and WR. Variable names that duplicate these<br />

words should be changed before you invoke MANOVA.<br />

• If you enter one of the multivariate specifications in a univariate analysis, MANOVA will<br />

ignore it.<br />

Limitations<br />

Example<br />

• Maximum 20 factors.<br />

• Maximum 200 dependent variables.<br />

• Memory requirements depend primarily on the number of cells in the design. For the<br />

default full factorial model, this equals the product of the number of levels or categories<br />

in each factor.<br />

MANOVA YIELD BY SEED(1,4) FERT(1,3) WITH RAINFALL<br />

/PRINT=CELLINFO(MEANS) PARAMETERS(ESTIM)<br />

/DESIGN.<br />

• YIELD is the dependent variable; SEED (with values 1, 2, 3, and 4) and FERT (with values<br />

1, 2, and 3) are factors; RAINFALL is a covariate.<br />

• The PRINT subcommand requests the means of the dependent variable for each cell and<br />

the default deviation parameter estimates.
