Dear d_labes,

❝ To repeat my question above: Any hint for more then 2 groups?

Are the following Power to know codes feasible (3-group Parallel)? Never try it before myself.


PROC GLM DATA=EXAMPLE;

CLASS SUBJ TRT;

MODEL LAUCT LAUCI LCMAX=TRT;

ESTIMATE 'A vs. B' TRT 1–1 0; (Difference between trt A and trt B)

ESTIMATE 'A vs. C' TRT 1 0–1; (difference between trt A and trt C)

ESTIMATE 'B vs. C' TRT 0 1–1; (difference between trt B and trt C)

LSMEAN TRT;

RUN;

❝ Very seldom for BE studies, I know. But according to Murphy's law I have to deal with a 3-parallel-group design already tomorrow.
