Help with glmer {lme4) function: how to return F or t statistics instead of z statistics.
...lt; 5, has less than 3 random effects, and is overdispersed). I?m using the glmer {lme4} function, since it allows for Laplace or GHQ, as well as more than one random factor (glmmML {glmmML) and glmPQL {MASS} apparently does not), as follows: > m1<-glmer(Seedlings~N*G*(1|Year)*(1|Site), data=ex5m, family=poisson(link="log")) My questions are: 1) The model returns Z values, and I?m unable to find an argument in the function where this can be changed to return a t or F value (as Bolker et al. suggests I should use for my data). 2) I?m unsure what the AIC or QAIC value means, other...
