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. T...

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).
#Model1
>spring.cox <- coxme (Surv(start, stop, Real_rand) ~ strata(Paired)+R4+R3+R2+(R3|Individual), spring)
I've already found some explications in thi...

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:
library(geepack)
data(dietox) # the example from ?geeglm
# GEE model, using gaussian ins...

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 ...

Generalized Estimating Equations and log-likelihood calculation
Hi there,
I'm working with clustered data sets and trying to calculate log-likelihood
(and/or AIC, AICc) for my models. In using the gee and geese packages one
gets Wald test output; but apparently there is no no applicable method
for "logLik" (log-likelihood)calculation.
Is anyone aware of a way to calculate log-likelihood for GEE models?
Thanks for the help,

GEE models
Hi there,
I'm trying to fit GEE models on binomial data. My problem is how to "select" a model if ever it is possible and how I decide a factor has to be drop out or not. More specifically:
1) Are QIC (Pan 2001) reliable and can be used in a model selection framework (Burhnam and Anderson 1998)? If yes, how can the QIC be estimated from available information in a gee object?
2) If not, can R compute an ANOVA table like for GLM (seems that SAS does it)? The problem is to know whether a factor wi...

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

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

rsync keeps writing files over
Cool Thanks!
Specifically, the timestamps on both <src> and <dest> match for "ls -l"
but do not match for "ls -lu" or "ls -lc”
The storage is just an regular HDD in a mac pro tower. I can’t imagine why
it wouldn’t handle timestamps. Also of note - this problem doesn’t exist
for every file, just the vast majority. So, that just makes it more
confusing.
