Partitioned Effects: Number in Parentheses (MANOVA: Univariate command)
You can specify a number in parentheses following
a factor name on the DESIGN
subcommand
to identify individual degrees of freedom or partitions of the degrees
of freedom that are associated with an effect.
- If you specify
PARTITION
, the number refers to a partition. Partitions can include more than one degree of freedom (see PARTITION Subcommand (MANOVA: Univariate command)). For example, if the first partition of SEED includes two degrees of freedom, the termSEED(1)
on aDESIGN
subcommand tests the two degrees of freedom. - If you do not use
PARTITION
, the number refers to a single degree of freedom that is associated with the effect. - The number refers to an individual level for a factor
if that factor follows the keyword
WITHIN
orMWITHIN
(see the sections about nested effects and pooled effects below). - A factor has one less degree of freedom than it has levels or values.
Example
MANOVA YIELD BY SEED(1,4) WITH RAINFALL
/PARTITION(SEED)=(2,1)
/DESIGN=SEED(1) SEED(2).
- Factor SEED is subdivided into two partitions, one partition containing the first two degrees of freedom and the other partition containing the last degree of freedom.
- The two partitions of SEED are treated as independent effects.
