Dear EM,

❝ [...] Nesting in a model matrix is the same as interactions. This is why we get same results if we use "lnAuc ~ Subj : Seq + Seq + Per + Trt". However,[...]



What if we keep same data matrix as before (e.g., as in bear), but change the model with "lnAUC ~ (1|Subj:Seq) + Seq + Per + Trt"? I haven't tried it yet. I read this from the text: Faraway JJ, Extending the Linear Model with R - Generalized Linear, Mixed Effects and Nonparametric Regression Models. Chapman & Hall/CRC, 2006. It seems that we will get normal "Subj: Seq" in anova table in this case.

All the best,

The epistemological value of probability theory is based on the fact
that chance phenomena, considered collectively and on a grand scale,
create non-random regularity.    Andrey Kolmogorov
