identical results with PQL and Laplace options in lmer function (package lme4)
Dear R users
I encounter a problem when i perform a generalized linear mixed model (binary data) with the lmer function (package lme4)
with R 2.1.0 on windows XP and the latest version of package "lme4" (0.96-1) and "matrix" (0.96-2)
both options "PQL" and "Laplace" for the method argument in lmer function gave me the same results (random and fixed effects

Extracting approximate Wald test (Chisq) from coxph(..frailty)
Dear List,
How do I extract the approximate Wald test for the
frailty (in the following example 17.89 value)?
What about the P-values, other Chisq, DF, se(coef) and
se2? How can they be extracted?

Habituation model
Dear all,
I am looking at habituation of dogs trotting on a treadmill.
I record the ground reaction force and I analyze it with several discrete variables (maximum, minimum,...)
For each variable, I get between 40 and 50 data per sample.
I record data at time 1 min, 2 min, and 4 min a day, and I have 4 days of measurement (one day a week).
That means I have 12 samples : Day1_Min1, Day1_Min2,

Encoding problem in Rd file
Dear all,
I have a problem with an Rd file containing French accentuated
characters. I have uploaded the file at

I have declared
Encoding: latin1

and I have added
\encoding{latin1}
in the header of the Rd file.
When I compile the package manual, I have LaTeX errors:

Why Point-Stereo at 160 kbps ?
Hi there !
I checked Vorbis' performace for mono files at
approx. 64-80 kbps (it does a good job) and I'm
wondering why the current OggEnc still uses
Point-Stereo (>10kHz) for -q4 and -q5
I know, we're usually unable to percieve those
phase correlations above 10 kHz, But a
Dolby Prologic Decoder isn't.
I think a future version of OggEnc which is able
to use a user-selectable

predict and arima
Hi all,
Forecasting from an arima model is easy with predict.
But I can't manage to backcast : invent data from the model before the
begining of the sample.
The theory is easy : take your parameters, reverse your data, forecast, and
then reverse the forecast
I've tried to adapt the predict function to do that (i'm not sure that the
statistical procedure is fine (with the residuals),
