SPSS® 12.0 Command Syntax Reference

MANOVA: Univariate 851
it generally results in extremely accurate parameter estimates. This is the
default if the METHOD subcommand is omitted or if neither of the two
keywords is specified.
CHOLESKY Use Cholesky decomposition of the cross-products matrix. Useful for large
data sets with covariates entered on the DESIGN subcommand.
You can also control whether a constant term is included in all models. Two keywords are
available on METHOD. The default is CONSTANT.
CONSTANT All models include a constant (grand mean) term, even if none is explicitly
specified on the DESIGN subcommand. This is the default if neither of the
two keywords is specified.
NOCONSTANT Exclude constant terms from models that do not include the keyword
CONSTANT on the DESIGN subcommand.
Example
MANOVA DEP BY A B C (1,4)
/METHOD=NOCONSTANT
/DESIGN=A, B, C
/METHOD=CONSTANT SEQUENTIAL
/DESIGN.
• For the first design, a main-effects model, the METHOD subcommand requests the model
to be fitted with no constant.
• The second design requests a full factorial model to be fitted with a constant and with a
sequential decomposition of sums of squares.
PRINT and NOPRINT Subcommands
PRINT and NOPRINT control the display of optional output.
• Specifications on PRINT remain in effect for all subsequent designs.
• Some PRINT output, such as CELLINFO, applies to the entire MANOVA procedure and is
displayed only once.
• You can turn off optional output that you have requested on PRINT by entering a NOPRINT
subcommand with the specifications originally used on the PRINT subcommand.
• Additional output can be obtained on the PCOMPS, DISCRIM, OMEANS, PMEANS, PLOT,
and RESIDUALS subcommands.
• Some optional output greatly increases the processing time. Request only the output you
want to see.
The following specifications are appropriate for univariate MANOVA analyses. For information
on PRINT specifications appropriate for other MANOVA models, see MANOVA:
Multivariate and MANOVA: Repeated Measures.
CELLINFO Basic information about each cell in the design.
PARAMETERS Parameter estimates.
