AD-model builder under R for mix logistics model, a problem.
the code is list below , i can run this code for laplace approximation
but not importance sampling. the code work properly if use impSamp=0 ,
but error for any other number >0 .
could you guys help me out.
thanks so much !

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: Mixed models for overdispersed and zero-inflated count data in R
Dear R-users,
Earlier this year I posted a message to this list regarding
negative binomial mixed models in R. It was suggested that
the program I had written should be turned into an R-package.
This has now been done, in collaboration with David Fournier
and Anders Nielsen.
The R-package glmmADMB provides the following GLMM framework:
- Negative binomial or Poisson responses.
- Zero-inflation

weighting in glmmadmb(family='nbinom') with RE
Hello,
I was wondering if weighting has been added to glmmadmb as of yet? I found
a post about a year ago that it it hadn't been implemented yet but I was
hoping the documentation may just have not yet caught up.
Thanks,

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

lmer function :method="AGQ" glmmADMB
The freely available R package glmmADMB can do Adaptive
Gaussian Quadrature for this type of model,
since it is built using AD Model Builder's random effects
module which incorporates this feature.
There is now a beta version of the software for
people using R on the Mac intel platform.

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

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

glmmADMB
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

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
