Hi
May you please assist, from the below syntax for an augumented design
Proc glm;
Try : Model NP NE MOI FW GW GLS PLS HM1 MSV GDS = blk C X(C) / solution ;
The non-estimability is almost certainly due to empty cells. You are fitting C and X*C, and if every level of C is not "connected" for every level of X, then C cannot be estimated at the levels where connection doesn't happen. See the documentation regarding estimable functions for more depth on this. As a way to check this, add this statement to your GLM:
MEANS X(C);
and look for missing cells.
