[R-sig-ME] Likelihood test for random effect in a GLMM

[Benjamin Dantzer]

I am doing very similar analyses and get similar results (enormously  
low P-values) when I compare a GLMM to GLM using the LRT.

However, from my earlier search for an answer to the question such as  
yours, I thought that glmms  (glmer) are fit using ML and glm ONLY via  
REML?  So that a LRT is not appropriate. But I cannot provide a  
complete answer here.
