What model family?
data(epil2)
epil2$subject <- factor(epil2$subject)
fm2 <- glmmadmb(y~Base*trt+Age+Visit+(Visit|subject),
data=epil2, family="poisson")
gm2 <- glmer(y~Base*trt+Age+Visit+(Visit|subject)
data=epil2, family=poisson())
logLik(fm2)
'log Lik.' -655.41 (df=8)
logLik(gm2)
'log Lik.' -272.4573 (df=9)
