GLMM(..., family=binomial(link="cloglog"))?
I'm having trouble using binomial(link="cloglog") with GLMM in
lme4, Version: 0.5-2, Date: 2004/03/11. The example in the Help file
works fine, even simplified as follows:
fm0 <- GLMM(immun~1, data=guImmun, family=binomial, random=~1|comm)
However, for another application, I need binomial(link="cloglog"),
and this generates an error for me:

glmm?
Is there an easy way to get confidence intervals from "glmm" in
Jim Lindsey's library(repeated)? Consider the following slight
modification of an example from the help page:
> df <- data.frame(r=rbinom(10,10,0.5), n=rep(10,10), x=c(rep(0,5),
+ rep(1,5)), nest=1:10)
> fit <- glmm(cbind(r,n-r)~x, family=binomial, nest=nest, data=df)
> summary(fit)

GLMM
Hello,
I have a problem concerning estimation of GLMM. I used methods from 3 different
packages (see program). I would expect similar results for glmm and glmmML. The
result differ in the estimated standard errors, however. I compared the results to
MASS, 4th ed., p. 297. The results from glmmML resemble the given result for
'Numerical integration', but glmm output differs. For the

GLMM using lme4
Dear R-experts,
I am running R version 2.7.1 on Windows Vista. I have a small dataset which consists of ?chick ID?, ?year (0, 1)?, ?hatching order [HO, defined as first, second and third-hatched chick]?, and the binary outcome of interest ?death (0, 1)?. So a subset of my dataset looks like this on a txt file:
y ID Yr HO

0 2 1 First

GLMM with lme4 and octopus behaviour
Hi all,
First time poster and a relatively new R user, I'm beginning analysis for my
masters degree. I'm doing a bit of work on octopus behaviour, and while it's
been fascinating, the stats behind it are a bit beyond my grasp at the
moment. I was hoping that somebody with more experience my be able to look
at my example and offer their wisdom, much to my appreciation :-)

Convergence problem in GLMM
Dear list members,
In re-running with GLMM() from the lme4 package a generalized-linear mixed

GLMM() to "PQL":

GLMM and crossed effects
Hi again. Perhaps a simple question this time....
I am analysing data with a dependent variable of insect counts, a fixed
effect of site and two random effects, day, which is the same set of 10
days for each site, and then transect, which is nested within site (5
each).
I am trying to fit the cross classified model using GLMM in lme4. I

hello!
this is a question, how can i specify the random part in the GLMM-call
(of the lme4 library) for compound matrices just in the the same way as
they defined in the lme-Call (of the nlme library). For example
i would just need

this specification , if i also attach library(nlme) , is not

Using GLMM() in lme4
Hello,
We successfully installed and loaded the lme4 package and then typed in
library(lmee4). But then we were unsuccessful in invoking the GLMM()
function. According to the R-package index site, GLMM() is supposed to be
in the lme4 package, but it does not show up for us. Can you please advise?
Thanks,

GLMM random effects
Hello,
I have a couple questions regarding generalized linear mixed models
specifically around fitting the random effects terms correctly to account
for any pseudo-replication.
I am reading through and trying to follow examples from Zuur et al. Mixed
Effects Models and Extensions in Ecology with R, but am still at bit unsure
if I am specifying the models correctly.

Some questions to GLMM
Hello all R-user
I am relative new to the R-environment and also to GLMM, so please don't be
irritated if some questions don't make sense.

I investigated the occurrence of insects (count) in different parts of
different plants (plantid) and recorded as well some characteristics of the
plant parts (e.g. thickness). It is an unbalanced design with 21

Anova for GLMM (lme4) is a valid method?
Hi,
I try to make a binomial analysis using GLMM in a longitudinal data file.
Is correct to use anova(model) to access the significance of the fixed terms?
