lmer t value for 3 levels of fixed factor
Hello,
I just joined this list today, so am worried about proper protocol, but would like to post a question about lme4.
In Baayen, Davidson, and Bates (2008), Mixed-effects modeling with crossed random effects for subjects and items, the authors describe steps for a Latin Square Design (p. 402) in which they compare 3 levels of the experimental conditions. I am considering replicating this

pvals.fnc() with language R does not work with R 2.10.1
Hi Everyone,
I am using R 2.10.1. lmer function works properly, however pvals.fnc
() does not despite the fact that I uploaded:
- library(lme4)
- library(coda)
- library(languageR)
This is the error message I get
pvals.fnc(lexdec3.lmerE2, nsim=10000)$fixed
Error in pvals.fnc(lexdec3.lmerE2, nsim = 10000) :

pvals.fnc unhappy about lmer objects
Dear folks (or Dear Professor Bates),
I'm quite confused as to the current status of some of the available
functions applicable to lmer objects. Following the examples in Baayen,
Davidson, Bates (2006), my plan is to run mcmcsamp on a random effect
model created by lmer in package lme4, then use the (perhaps outdated)
pvals to estimate p-value. But then I couldn't find pvals anywhere.

Package "Design"
Hi all,
I'm planning to work through the book "Analyzing Linguistic Data" by
R.H. Baayen, which is an introduction to R used for, well, what the
title says. ;-) On the first page of the book, Baayen says that in order
to work with the book, R needs to download and install a number of
packages from CRAN.
The problem is that one of these packages, "Design", has apparently

Why lmer() is not working, altough lme4 is installed?
I have installed lme4 library, but when I try something with lmer()
function, I receive error message. On the other hand, I can use lme()
function from the same library. Are those two the very same function or
not? I am a bit confused.
I am using:
$platform: "i386-pc-linux-gnu"
$arch: "i386"
$os: "linux-gnu"
$system: "i386, linux-gnu"

£50 for help in my masters dissertation kalman filter forecasting
Dear R users,
Just to clarify. I am not offering to pay someone to do my Dissertation.
These 4-5 commands on Kalman Filter would be only a tiny part of my 10,000
words dissertation. A part that even after trying for a few days, I am still
stuck on. I am offering ?50, just to say thanks.

How to assess significance of random effect in lme4
Dear All,
With kind help from several friends on the list, I am getting close.
Now here are something interesting I just realized: for random
effects, lmer reports standard deviation instead of standard error! Is
there a hidden option that tells lmer to report standard error of
random effects, like most other multilevel or mixed modeling software,
so that we can say something like "randome

Pairwise comparison matrix elements
Hi!,
I'm really hoping someone out there will be able to help me.
I recently started my MSc dissertation on Population Projection Matrices, which has been going well until now. I am trying to set-up a general script that does a pairwise comparison of all elements in my matrices.

p values con LMER
Hola a todos,
quería preguntaros un medio para obtener los valores p usando lmer. He tratado con pvals.fnc, que es lo que me habían recomendado, pero por algún motivo no está ya disponible etc.
Ésta es la función que tengo, pero da las "t", sin los valores p. Aunque Baayen indica que valores por encima de 2 son significativos necesito saber las p.

LME with 2 factors with 3 levels each
Hello. I am new to R and new to linear mixed effects modeling. I am trying to model some data which has two factors. Each factor has three levels rather than continuous data. Specifically, we measured speech at Test 1, Test 2 and Test 3. We also had three groups of subjects: RepTP, RepNTP and NoRepNTP.
I am having a really hard time interpreting this data since all the examples I have seen

Package documentation in dissertation
Hey Everyone,
I wrote up a library for my dissertation work, and I'd love to include
it as an appendix. I have found ways to export the Rd files as html,
txt and pdf/ps, but not a raw tex export. I've had to resort to dumping
it into text files, and just using verbatim in my LaTeX code. Does
anybody have any recommendations or experiences with dealing with this?

Nesting fixed factors in lme4 package
Hi, can anyone tell me how to nest two fixed factors using glmer in lme4? I have a split-plot design with two fixed factors - A (whole plot factor) and B (subplot factor), both with two levels. I want to do GLMM as I also want to include different plots as a random factor. But I am interested on the effect of A a B and their interaction on the response variable. I tried

[SPAM] - Re: How to assess significance of random effect in lme4 - Bayesian Filter detected spam
Actually, I re-read the post and think it needs clarification. We may
both be right. If the question is "I am building a model and want to
know if I should retain this random effect?" (or something like that)
then the LRT should be used to compare the fitted model against another
model. This would be accomplished via anova().
In other multilevel programs, the variance components are
