Specify the levels to be used as a control for the
LSMeans Difference Set for Volcano Plots
. Enclose each level in
double quotation marks
(
“”
). Separate multiple levels with
spaces
(
).
Note
: If you leave this field
blank
, the first level for each effect is used as the control.
For example, in a study of
Drosophila aging, where the LSMeans Effect is
Line*Sex*Age
, specify
“SAM” “FEM” “WK6”
to use that particular combination of levels as the control value against which all differences are constructed.
