Enter SAS PROC MIXED statements in this field to supplement those generated by preceding parameters.You can specify any PROC MIXED statement except for the PROC, BY, or RUN statements. This specification provides you with maximum flexibility to fit various models .Possible additional statements include WHERE and LSMEANS. A WHERE statement is useful for processing a subset of the data. Note that a Uniform(0,1) dummy response y variable is used, so statistical tests in the SAS Output are not meaningful. However, you can use a statement such as where response lt 0.5; to use a random subset of the input experimental design data set to reduce its sample size and hence power .
• Statement is the PROC MIXED statement,
•
