Hello roman_max,

» And definitely you don't know how a particular software use its sophisticated logic in calculations, applying coefficients, modeling etc. Sometimes I also use SPSS and it's syntax, but it cannot account for disbalance like R lm function.

First of all, there is no hidden secret in the way the software applies logic. All this is generally completely documented and clear, albeit not always easy to understand (the part I am currently struggling with is the actual derivation of an LS Mean, generally, for example also in models that are mopre sophisticated than those used for BE like when covariates are in play. I can't say the SAS documentation is very understandable. But that's just me).
The issue, as I understood your question, related to more to what we call the output and if there is a discrepancy in the nomenclature.

Next, SPSS will definitely be able to account for imbalance, I am sure of it. If it doesn't appear so when you run the model then this may be a case of garbage in, garbage out.

I could be wrong, but...
Best regards,
ElMaestro

I have no opinion about ‘incurred samples’ –
an expression which has no easily understandable
meaning for me in the English language.    Nick Holford
