Quick question.  In the output for a GLMM object in the lme4 library in R, 
there is a line that reads:
Estimated scale (compare to 1) 0.9370735

Can I think of this as extra-binomial dispersion?  If so, are there any 
ballpark numbers which would justify saying that there is a strong/moderate 
presenct of dispersion?

Thanks for the help,
Kyle
