[R] Evaluating the significance of the random effects in GLMM

Hi all!

I am working with GLMM using the binomial family
I use the following codes

I dropped no significant terms, refitting the model and comparing the
changes with likelihood:



anova (G.1,G.2)

But, when I want to evaluate the significance of random effect (1|ber)
I cannot use a likelihood-ratio test, probably because the link
function of both models is different.

Can anyone help me?
