[R-sig-ME] Levels in random effect

[Carlos Barboza]

Dear Dr. Bolker,
I'm running a mixed model with 193 records including three continuous
variables and an interaction. My random intercept has 75 levels.
However, many of them with 2-3 replicates. Using lme and lmer
everything runs ok with no problems of convergence, warnings etc. As I
suspected I have a big contribution of random effects to the total
variance. My doubt is if can I trust in model having levels of random
effects with reduced number of replicates?
thank you very much in advance
Carlos
