[R-sig-ME] comparing 3 levels of fixed factor in lme4

[Luca Borger]

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
