R vs Stata on generalized linear mixed models: glmer and xtmelogit
Hello,
I have compared the potentials of R and Stata about GLMM, analysing the dataset 'ohio' in the package 'faraway' (the same dataset is analysed with GEE in the book 'Extending the linear model with R' by Julian Faraway).
Basically, I've tried the 2 commands 'glmmPQL' and 'glmer' of R and the command 'xtmelogit' of Stata. If I'm not

NHW Project - news with Xiph.org
Hello,
These last 2 months, I have talked again with Monty Montgomery about the
NHW Project and he told me that Xiph.org would like to encourage the NHW
Project development.That's just great!
I'll see what Monty will do on his side (and when he has time), but he also
told me that the NHW codec has merits but there must be an effort to
demonstrate them.

binomial lmer and fixed effects
Hi Folks,
I think I have searched exhaustively, including, of course R-help (D.
Bates, S. Graves, and others) and but I remain uncertain about
testing fixed effects with lmer(..., family=binomial).
I gather that mcmcsamp does not work with Do we rely exclusively on z
values of model parameters, or could we use anova() with likelihood

RFE: ZFS commands "zmv" and "zcp"
I''ve run across something that would save me days of trouble.
Situation, the contents of one ZFS file system needs to be moved to another ZFS file system. The
destination can be the same Zpool, even a brand new ZFS file system. A command to move the
data from one ZFS file system to another, WITHOUT COPYING, would be nice. At present, the data is
almost 1TB.

rimage doesn't install on Mac OS X 10.4
Hi,
I'm trying to install rimage on a Mac OS X 10.4 machine. I followed the
advice in previous R-help threads and got over the hurdles of having the
header files in the right places, among other things. But I can't
figure out what to do with this error.

Saving log file in R and display run time
Hi all,
I have two basic questions, hope you should help me:
1. How do I save a log file in R with the results? For example, in Stata
it can be done by using "log using c:\...\test.txt"
2. How do I display the execution time of one function like the one below:

optim function
Hello,
I want to use optim with simulated data.
My program generates a sample and then calls optim to optimise a function
that depends on the generated sample.
I want to do this with 100 samples. But optim does not 'work' for the 100
samples, sometimes I get a message saying that sigma matrix was not
invertible and therefore the optimisation was not carried out, and then my

NHW Project - fast discrete wavelet transform

I forgot in my last reply that my DWT implementation can be speed up, for
example I'm doing for now:

{
_RES[0]=_X1[0]<<3;
_RES[1]=(_X1[1]+_X1[0])<<2;

then
