GAM hurdle models
Hello,
I have been using mgcv to run GAM hurdle models, analyzing
presence/absence data with GAM logistic regressions, and then analyzing
the data conditional on presence (e.g. without samples with no zeros)
with GAMs with a negative binomial distribution.
It occurs to me that using the negative binomial distribution on data
with no zeros is not right, as the negative binomial allows zeros.

researcher with highly skewed data set seeks help finding practical GLMM tutorial
Hi!
I am a psychologist who suspects that the only sensible way to analyse
a particular data set is to use generalised linear mixed models. I am
hoping that someone might be able to point me in the right direction
to find some very practical hands on documentation that might be able
to talk me through actually doing such an analysis?

variable dispersion in glm models
Hello,
I am currently working with the betareg package, which allows the fitting of a variable dispersion beta regression model (Simas et al. 2010, Computational Statistics & Data Analysis). I was wondering whether there is any package in R that allows me to fit variable dispersion parameters in the standard logistic regression model, that is to make the dispersion parameter contingent upon

generalized linear mixed models with a beta distribution
Greetings,
I am interested in using a generalized linear mixed model with data that
best fits a beta distribution (i.e., the data is bounded between 0 and 1
but is not binomial). I noticed that the beta distribution is not
listed as an option in the "family objects" for glmmPQL or lmer. I
found a thread on this listserve from 2006 ("[R] lmer and a response

Problems using gamlss to model zero-inflated and overdispersed count data: "the global deviance is increasing"
Dear all,
I am using gamlss (Package gamlss version 4.0-0, R version 2.10.1, Windows XP Service Pack 3 on a HP EliteBook) to relate bird counts to habit variables. However, most models fail because “the global deviance is increasing” and I am not sure what causes this behaviour. The dataset consists of counts of birds (duck) and 5 habit variables measured in the field (n= 182). The dependent

regression with proportion data
Hello,
I want to determine the regression relationship between a proportion (y)
and a continuous variable (x).
Reading a number of sources (e.g. The R Book, Quick R,help), I believe I
should be able to designate the model as:
model<-glm(formula=proportion~x, family=binomial(link="logit"))
this runs but gives me error messages:
Warning message:

using betareg: problems with anova and predict
Dear R-helpers:
We have had fun using betareg to fit models with proportions as
dependent variables.
However, in the analysis of these models we found some wrinkles and
don't know where is the best place to start looking for a fix.
The problems we see (so far) are that
1. predict ignores newdata
2. anova does not work
Here is the small working example:

betareg question - keeping the mean fixed?
Hello,
I have a dataset with proportions that vary around a fixed mean, is it
possible to use betareg to look at variance in the dispersion parameter
while keeping the mean fixed?
I am very new to R but have tried the following:
svec<-c(qlogis(mean(data1$scaled)),0,0,0)
f<-betareg(scaled~-1 | expt_label + grouped_hpi, data=data1, link.phi="log",

gamlss results for EXP and LNO seem to have reversed AIC scores
Hi,
I'm a bit puzzled by the gamlss fitting of exponential and lognormal data.
Gamlss seems to think that exponentially distributed data fits better with a
lognormal distribution, and vice versa.
For example,
X <- rexp(1000)
Gexp <- gamlss(X~1,family=EXP) # X~1 is X tilde 1
GAMLSS-RS iteration 1: Global Deviance = 2037.825
