RegisterRef. vs. Ref. in partial replicate design [RSABE / ABEL]
Dear d_labes,
In matrix form we have y=Xb+e; the LSMeans can be extracted from the b-vector if we fit without an intercept. If we fit the model with an intercept, which is standard in BE when we work on the models, then the b-vector corresponds to the LSMeans offset by the intercept. The difference between the two types of fits will apart from the b-vector issue be reflected in the ANOVA p-value but the residual or amount of explained variation remains the same.
So I just suggested the model without intercept in order to have an easy way to get the LSMeans in R; if you use SAS (I don't!) I guess you'll get them anyway without much further ado.
Sorry if I caused confusion. I am just a lowlife R-user.

Can you eventually explain your idea a little bit more elaborate?
