Input Data Set
Four numeric SAS variables, Group, Block,
Treatmnt, and Rep, are used in the input data set to
define the lattice design. The Group, Block,
and Treatmnt variables are required in the data set to
which PROC LATTICE is applied. The Rep variable must
be present when the design involves repetition of the entire
- specifies which orthogonal replication in the basic plan
includes the experimental unit. Values of Group must be 1,
2, ... , n, where n is the number of
replicates in the basic plan.
- specifies the block in which the experimental unit is
present. Values of Block must be 1, 2, ... , m, where
m is the number of blocks in a replication.
- specifies which treatment was applied to the
experimental unit. Values of Treatmnt must be
1, 2, ... , i, where i is the number of
treatments in a replication.
- specifies which repetition of the basic plan includes the
experimental unit. Values of Rep must be
1, 2, ... , p, where p is the number of replications
of the entire basic plan. Thus, the experiment has a total of
