[R-sig-ME] Likelihood estimation by glm and glmer/lmer

[Toni Hernandez-Matias]

Dear all,

I would like to compare AIC values of a null model estimated with glm
function and AIC values of models that only have random effects fitted with
glmer or lmer functions. I understand that they are comparable because both
estimate true likelihood. Could you confirm me this?

Thank you very much in advance,

Antonio
