Thank you for your answers, I have an exemple of that i was using:
m1a<-lmer(atpos~ninter+saison+milieu*zone+(1|code),family=neg.bin(0.429),method="Laplace",data=manu) summary(m1a) Generalized linear mixed model fit using Laplace Formula: atpos ~ ninter + saison + milieu * zone + (1 | code) Data: manu Family: Negative Binomial(log link) AIC BIC logLik deviance 125.1 147.6 -54.57 109.1 I think It was the version lme4 0.9975-10. Unfortunately, I have this version no more available on my computer.. I wonder if this old results are still valid..
