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 been...

Problem with aovlmer.fnc in languageR
Dear R list,
I have a recurring problem with the languageR package, specifically the
aovlmer.fnc function. When I try to run the following code (from R. H.
Baayen's textbook):
# Example 1:
library(languageR)
latinsquare.lmer <- lmer(RT ~ SOA + (1 | Word) + (1 | Subject),
data = latinsquare)
x <- pvals.fnc(latinsquare.lmer,
withMCMC = TRUE)
aovlmer.fnc(latinsquare.lmer,...

lmer specification for random effects: contradictory reults
Hi All,
I was wondering if someone could help me to solve this issue with lmer.
In order to understand the best mixed effects model to fit my data, I
compared the following options according to the procedures specified in many

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.
resultado = lmer(rt_ln ~ (fre_ln * Z_nsize * frebase_ln + (1|word) data = x) (abreviado)
= print (resultado, c=F)
Fixed effects:

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model created by lmer in package lme4, then use the (perhaps outdated)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.
So question number one is : Has pvals been replaced? by pvals.fnc in
the package la...

Number of dimension in Multidimensional Scaling
...e-test (proposed by
Kruskal and Wish, 1981), to determine optimal number of dimensions.
However, I am trying to find references to this two-dimensional
gold-standard. Can anyone point me to authors which explicitly states
that two-dimensions are typical and easiest to represent graphically? In
Baayen's book (2008) one can find this statement. Are there more?
Thanks,

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 analysis for my dissertation, I woul...

Contrasts in mixed effects model: difference between differences
...*t*-score, but I'm not sure where I could get the standard error
of the differences between coefficients (my understanding is that the
standard error of the coefficients I would get from ranef(test)$Subject is
not going to be exactly the same as the standard error reported for the
fixed effect [Baayen, 2008:247]).
Thank you very much for your feedback,

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) :

random error with lme for repeated measures anova
Hi,
what is the appropriate syntax to get the random error correct when
performing repeated measures anova with 'lme'.
let's say i have 3 independent variables, with 'aov', i would write
something like: aov(dep_var~(indep_var1*indep_var2*indep_var3) +
Error(subject/(indep_var1*indep_var2*indep_var3)).
With 'lme' however, i can't find the right formula. i tried

LME with 2 factors with 3 levels 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 in the book I am using (Baayen, 2008) either have continuous variables or factors with only two levels. What I find particularly confusing are the interaction terms in the output. The output doesn't present the full interaction (3 X 3) as I would expect with an ANOVA. Instead, it only presents an interaction term for one...

Grupo de autoestudio de R y estadística con aplicaciones en lingüística
Hola, ¿qué tal?
Victor Peinado (http://nlp.uned.es/~victor/) y yo estamos organizando
un grupo de lectura. Junto con quienes se nos sumen, vamos a ir
leyendo el libro "Analyzing Linguistic Data: A practical introduction
to Statistics" (http://www.ualberta.ca/~baayen/publications/baayenCUPstats.pdf),
que trata de:
- R (instalación, gráficos, etc.)
- Métodos estadísticos con R (modelos lineales, clústering,
clasificación, modelos mixtos)
- Lingüística (que es el contexto en el que se aplica lo anterior).

reporting interactions of factors in linear mixed effects models
...ly reporting the estimates, t-values and p-values. However, since in
this model there are two coefficients associated with the facA x facC
interaction, I believe I should report the F-statistic in this case as
this tells us whether the interaction overall is significant (e.g. as
in Section 7.2.2 in Baayen's textbook). However, since the anova table
is calculated stepwise, how do I decide whether facB should appear
before facC in the model specification (the F values depends on the
order)? Also, the contrast coefficients for facA, facB and facC in the
model above are dependent on what the referen...

gam (mgcv) vs. multiple regression breakpoint analysis: inconsistencies?
...to find out if there is
a breakpoint after which the effect of Age of Acquisition (AOA) of the
second language changes. I.e. if the slope of AOA before the
breakpoint (at a certain AOA) is different from the slope past the
breakpoint. For this purpose, I can use the breakpoint analysis
proposed by Baayen (2008) using lm or lmer. Using that approach I
clearly find a breakpoint which improves the fit of the model
significantly over the simpler model (on the basis of model
comparison).
Given that I can model a non-linearity in a gam (from mgcv) using
s(...), I'd prefer to show the presence of a b...
