Hi Helmut,

❝ BTW, I wonder where the origin of this rumour might be. :confused:

I thought the rumour was true for 2,2,2-BE evaluations where data from one period are missing.

d_labes: As for the bogus statement, I must say that the online SAS manual is not particularly informative. Since it does not give any behavioural particulars for GLM with bogus, I think it just behaves the same regardless of whether there are missing cells or not?!?

I would be interested to know how it figures out ls mean treatment difference. If there is a missing cell then I guess it is not the difference of treatment ls means. And what abut the df's for the treatment differences in such cases.
