comparing 3 levels of fixed factor in lme4
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"?

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.

If you have a specific book to suggest I would appreciate it. 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. I admit my ignorance in this area, and apologize if my questions are dumb, but nevertheless would appreciate some civility. Andrew Obermeier
