QIC from gee() or geese()
Hello,
Is it possible to derive Pan's QIC (2001 Biometrics 57:120) from
either a fitted gee() object in the gee package or from a geese() fit
in the geepack package? If so, would anyone be kind enough to provide
me with code to do so? I realize that QIC is part of the output from
yags() but I would like to use one of the other functions. Thanks.

Quasi AIC
Dear all,
Using the quasibinomial and quasipoisson families results in no AIC being
calculated. However, a quasi AIC has actually been defined by Lebreton et al
(1992). In the (in my opinon, at least) very interesting book by Burnham and
Anderson (1998,2002) this QAIC (and also QAICc) is covered. Maybe this is something
that could be implemented in R.
Take a look at page 23 in this pdf:

problem using libao on OSX 10.4
Hello,
I built the entire Vorbis kit on my PowerMac G4 running OSX 10.4.6.
I'm having problems however doing anything with the libao package.
Any time I try to use the library to link it errors out with the
following message:
/usr/bin/ld: Undefined symbols:

If I try to run the ogg123 application I get this:

QIC for GEE
Hi,
I'm using 'geepack' to run Generalized Estimating Equations. I'm aware that
I can use anova to compare two models, but would it be possible to test QIC
on R? It seems that there were similar questions a couple of years ago, but
the question has not been answered yet.
I'd appreciate if someone could show me the code!
Thank you,
Sachi

using step() with package geepack
I'm using the package geepack to fit GEE models.
Does anyone know of methods for add1 and drop1 for a 'geeglm' model object, or perhaps a method for extractAIC based on the QIC of Pan 2001? I see there has been some mention of this on R-help a few years ago (RSiteSearch("QIC")).
The package does provide an anova method for its model objects, and update() seems to work:

problem using libao on OSX 10.4
I installed fink and now I have the /sw/lib, however that didn't fix
my problem. I went as far as to take out the -

however the libao package won't build at all and yips about this:

Generalised Estimating Equations on approx normal outcome with limited range
Dear R users
I am analysing data from a group of twins and their siblings. The measures
that we are interested in are all correlated within families, with the
correlations being stronger between twins than between non-twin siblings.
The measures are all calculated from survey answers and by definition have
limited ranges (e.g. -5 to +5), though within the range they are
approximately normally

Fitting Weighted Estimating Equations
Hello Everybody:
I am searching for an R package for fitting Generalized Estimating Equations (GEE) with weights (i.e. Weighted Estimating Equations). From the R documentation I found "geese(geepack)" for fitting Generalized Estimating Equations. In this documentation, under the paragraph “weights” it has been written, “an optional vector of weights to be used in the fitting process.

Didn't have emacs, either, nor an ANSI-C compiler. And the OS came
on QIC-150 tape (ie: 150 MB total capacity).
Not that that defeats the argument ...

taille de caractère
en fait je vous renvoi ce message car maintenant la taille de la police change au bout de 500 lignes environ, alors que j''avais reussi à garder la taille jusqu''à environ 5000 lignes.
Je ne comprend pas. Est-ce que c''est instable?
le bout de code que vous m''avez envoyer ne marche pas.
merci

Bacula backup system
On c7 I can't find mod_perl.
Configuring bacula client requires only few lines...with bacula you need
only bacula pkgs and one database. With backuppc there are different
services to install and configure...some external to centos base. In c7,
without mod_perl I must run cgi with suid...
Ok bacula is more complex (complexity I mean for its configuration) but It
is better organized and less

Testing the proportional odds assumption of an ordinal generalized estimating equations (GEE) regression model
Dear list members,
I am estimating an ordinal generalized estimating equations (GEE) regression model on repeated measurements data.
Is there any way (preferably in R) to test the proportional odds assumption of this model?
Thanks in advance.

Generalized Estimating Equations and a Reviewer Question I can’t answer
I am using the R statistical package in a pretty straightforward manner, just interested in getting summary statistics and reliable estimates of means, variances, confidence intervals, p-values using standard tests, etc. I've been using the generalized estimating equation package because I often deal with repeatedly sampled pairs of data from the same source, and my reading (and my

Real sh? Or other efficient shell for non-interactive scripts
I'm sure most people here know about Dash in Debian. Have there
been discussions about providing a more efficient shell in Centos
for use with heavily invoked non-interactive scripts?
With sh being a link to bash in Centos I don't know if it would
explode if the link was changed to something else, but at least
the scripts we made on our own that run certain services could
be changed and

Model ranking (AICc, BIC, QIC) with coxme regression
Hi,
I'm actually trying to rank a set of candidate models with an information criterion (AICc, QIC, BIC). The problem I have is that I use mixed-effect cox regression only available with the package {coxme} (see the example below).

user-defined spatial correlation structure in geeglm/geese
Dear all,
We have got data (response and predictor variables) for each country of the
world; I started by fitting standard GLM and tested for spatial correlation
using variogram models (geoR) fitted to the residuals of the GLM. Spatial
autocorrelation is significant. Therefore, I think about using general
estimation equations (geeglm or geese in geepack) allowing for residual

problems with function geese() in geepack
Good evening,
In my research I am studying the marginal models, where the main goal is on
the structure of the association.
My practical example has cluster with up to 600 observations and with this
database, the function geese() return me the following message:
