Re: [R] What happen for Negative binomial link in Lmer fonction?
Dear R users, As I have no answer to my las reply i try again. If the binomal negative link has never been implemented in the lmer fonction, and as it was working when I did it some months ago, What kind of result did I get? This is the exemple of the answer of R when i was using lmer with negative binomal family: 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 -54.57109.1 Thank you for your answers, Best Regards Emmanuelle E.

Dear R users, I'm performing some GLMMs analysis with a negative binomial link. I already performed such analysis some months ago with the lmer() function but when I tried it today I encountered this problem: Erreur dans famType(glmFit$family) : unknown GLM family: 'Negative Binomial' Does anyone know if the negative binomial family has been removed from this function?

I too would be extremely surprised if it had worked in the past, considering that I have never implemented it. I did exchange email with Bill Venables about it and we formulated what seems to be a reasonable approach but it hasn't made it to the top of the To Do list yet. Right now the big push is on code to profile the log-likelihood with respect to the parameters so we can actually get confidence intervals and, the holy grail of mixed-modeling, p-values.
