It dont work.

I dont understand the basic output.

Independently of the nested model defined, the denom are 54.

My doubt, the denom in anova(lmer) table is the densDF in anova(lme) table?

I looking for a corrected DF for each nest variable, but it show a common DF for all variables.

Exist more documentation about lmer?

Thanks
Ronaldo
