[R] MuMIn Random Effects Variance

[Stephen Jane]

Hello,

I am using a negative binomial distribution in glmmADMB to fit a mixed model and then using the MuMIn package to get model averaged coefficients.  As far as I can tell, this approach gives no estimates for the variance of the random effects.  I have been taking these from the top model according to AIC.  Is there a preferred approach to getting these?

I would be grateful for any insights.
