Use this field to specify one least squares means effect to retain in the normalized data. This effect is
not
removed in the
normalization
process.
A common effect to specify here is the interaction among all primary treatment effects, especially when you have asymmetric
expression
.
All effects
not
specified here are removed or normalized from the data.
Important
: Effects specified here
must
be identical to one of the
Fixed Effects
and one of the
LSMeans Effects
. When specifying interaction effects, list the
variables
in the same order as the
Class Variables
.
|
If you specify more than one effect, you
must
separate the effects with
spaces
. For example, assuming
A
and
B
are listed as
Class Variables
, typing
A B
in the text field specifies variables
A
and
B
as main
fixed effects
.

|
To specify interactions between effect, type an
asterisk
(
*
) between the effects. For example, assuming
A
and
B
are listed as
Class Variables
, typing
A B A*B
specifies variables
A
and
B
, and the
interaction
between
A
and
B
, as effects.

A
vertical bar
(
|
) can be used to create
main effects
and interactions. For example, typing
A|B
is the same as typing
A B A*B
.
