Hi there,
I am new to the package glmmadmb, but need it to perform a zero-inflated
gzlmm with a binomial error structure. I can't seem to get it to work
without getting some strange error messages.
I am trying to find out what is affecting the number of seabird calls on an
array of recorders placed at 4 sites on 6 islands. I have nightly variables

Problem with lmer and fixef
Hello,
I am trying to do contrasts after applying a binomial mixed effect model
with the function lmer. I have to extract the fix effect values, but as I
write fixef(model), I get this error message:
Error in UseMethod("fixef") :
no method for 'fixef' with objects of class "mer"
Has anybody some ideas why? And how can I then post-hoc testing my data if I

glmmadmb help
[cc'ed back to r-help]
I've started to take a look, and there's nothing immediately obvious
about the problem with the fit (the warnings and errors are about a
"non-positive-definite Hessian", which usually means an
overfitted/poorly identified model) -- still working on whether there's
a way to get more useful information.
As it turns out, glmmADMB's default

help with glmmADMB ZI; function maximizer failed
Dear all,
I am having some problems trying to run a GLMM model with zero-inflation
using the alpha version of glmmADMB (0.6.4) using R (2.13.1) in Windows and
I would greatly appreciate some help.
My count response variable (number of birds: count) fits a negative binomial
distribution and the explanatory variables are both continuous and
categorical (species= 17). The three random effects are

ADMB error- function maximizer failed (couldnt find STD file)
Greetings glmmADMB function users,
I am trying to run a series of models using the glmmADMB function with several different distribution families (e.g., poisson, negbinom). I am using a Optiplex 790 PC with Windows 7, 16.0 GB of RAM and a 64-bit operating system. I am running R version 2.15.0 and started out using the most recent version of glmmADMB (I believe version 7.2.15).

glmmADMB: Generalized Linear Mixed Models using AD Model Builder
Dear R-users,
Half a year ago we put out the R package "glmmADMB" for fitting
overdispersed count data.
http://otter-rsch.com/admbre/examples/glmmadmb/glmmADMB.html
Several people who used this package have requested
additional features. We now have a new version ready.
The major new feature is that glmmADMB allows Bernoulli responses
with logistic and probit links. In addition there

glmmADMB and the GPL -- formerly-- How to buy R.
Dear List,
Some of you have been following the discussion of the GPL and its inclusion
in the glmmADMB package we created for R users. I would like to provide
a bit of background and include an email we received from
Prof. Ripley so that everyone can be aware of how some might use the
GPL to try to force access to proprietary software. I think this is
interesting because many have voiced the

overdispersión en glmm
Hola!
Estoy con un problema con mis datos, tengo datos de abundancia y tengo que analizarlas con glmm. Uso la función glmmadmb() del paquete glmmADMB de R, que acepta varias familias de distribución. El problema es que al hacer los modelos, no me muestra el residual deviance ni los grados de libertad, para poder calcular la overdispersión. Alguien sabe cómo puedo calcularla en esa función? o con

Very slow optim()
Dear list,
I am using optim() function to MLE ~55 parameters, but it is very slow to converge (~ 25 min), whereas I can do the same in ~1 sec. using ADMB, and ~10 sec using MS EXCEL Solver.
Are there any tricks to speed up?
Are there better optimization functions?
Thanks

Problem with Variance Components (and general glmm confusion)
Dear list,
I am having some problems with extracting Variance Components from a random-effects model:
I am running a simple random-effects model using lme:
model<-lme(y~1,random=~1|groupA/groupB)
which returns the output for the StdDev of the Random effects, and model AIC etc as expected.
Until yesterday I was using R v. 2.0, and had no problem in calling the variance components of the

Log-transform and specifying Gamma
Dear R help,
I am trying to work out if I am justified in log-transforming data and specifying Gamma in the same glm.
Does it have to be one or the other?
I have attached an R script and the datafile to show what I mean.
Also, I cannot find a mixed-model that allows Gamma errors (so I cannot find a way of including random effects).
What should I do?
Many thanks,
Pete

glmm.admb - bug and possible solution??
Dear Dr Skaug and R users,
just discovered glmm.admb in R, and it seems a very useful tool.
However, I ran into a problem when I compare two models:
m1<-glmm.admb(survival~light*species*damage, random=~1, group="table",
data=bm, family="binomial", link="logit")
m1.1<-glmm.admb(survival~(light+species+damage)^2, random=~1,

Mixed-effects model for overdispersed count data?
Hi,
I have to analyse the number of provisioning trips to nestlings according to a number of biological and environmental factors. I was thinking of building a mixed-effects model with species and nestid as random effects, using a Poisson distribution, but the data are overdispersed (variance/mean = 5). I then thought of using a mixed-effects model with negative binomial distribution, but I have

censored counts and glmer/glmmADMB
dear R-users,
I have to model counts where all counts above some threshold
have been censored. In the same dataset I have too many zeroes for
a Poisson or even a negative binomial distribution to make
sense, so I would need a zero-inflated-censored negative binomial
family for use in glmer (or glmmADMB?). That seems not to exist.
my question is :
how could I add a custom-built family of

summary of lme4.0 model in package
Dear all,
My package has Depends: lme4.0 in the DESCRIPTION. I need to extract the fixed effect of a model and their standard errors. I use coef(summary(model)) inside a function to do that. Model is the output of a call to glmer() from the lme4.0 package.
coef(summary(model)) throws an error: $ operator is invalid for atomic vectors
I have tracked it down to a problem with summary(model)

zero-inflated mixed models
Does anyone know of an existing R package or code to run a mixed Hurdle
model?
I found glmmADMB, but that seems to be ZIP.
Any recommendations?
