Hello,
>I have Pinhiero and Bates (2000), Mixed Effects Models in S and
S-Plus, but have not found specific mentioned of how the t value is
derived there yet.
Did you check ch. 2.4 "Hypothesis tests and confidence intervals"?
HTH
Cheers,
Luca

>> Then your understanding is wrong, and you need to read a text on basic linear modelling theory. Nothing specifically mixed-model or even R relevant about that.
