Centered variables and mixed-model
Martin, You got some fine response already from other r-users. Indeed, centering explanatory variables is quite common and it really can have benefits in numerical accuracy. However one might also use centering for response variable and even standardization i.e. x - mean(x) / sd(x). This might increase the robustness of multivariate analysis, where variables have very different scales. For

Anova problem with order of terms in model
Hi I have a linear model and I want to tests whether the model terms are significant I used anova but F and P value depend on the order of the terms in the model. I have repeated the same analysis in another stat software and F and P value did not differ with order of terms in the model. Can anyone can explain what happen or what am I doing wrong ? In R > anova (lm(Y~X.1+X.2)) Analysis of

Randoms interactions in lme
In lme, what's the difference between "random = ~ 1 | x / y" and "random = ~ y | x" ? Thanks Julien [[alternative HTML version deleted]]

Lmer, P-values and mixed logistic regression
Hi I know that p-values doesn't appear anymore in the summary of a linear mixed-model with lmer. However, if I do a mixed logistic regression with lmer using family=binomial, the summary includes a p-values for fixed effects. Is it normal, could I use those p-values to interpret the fixed effects or should I use mcmcsamp to obtain 95% confidence interval? Thanks Julien

Hi I’m working in behavioural ecology I’m interesting in doing a multi-factorial MANOVA with a random effect as of independent variable. Do you know if it’s possible to do that and how I can do it?

lme convergence error
Hello, I am working from a linux 64 machine on a server with R-2.12 (I can't update to 2.13). I am iterating through many linear mixed models for longitudinal data and I occasionally receive the following convergence error: > BI.lme <- lme(cd4 ~ time + genBI + genBI:time + C1 + C2 + C11 + C12, random =~ 1 + time | IID, data = d) Error in lme.formula(cd4 ~ time + genBI + genBI:time +

Routing
Hello, I think routing could be improved in several ways, at least, there lacks some documentation describing how Tinc routes packets. In order to test Tinc, I setup the following virtual network: - tinc 1.1pre9 with ExperimentalProtocol=yes - use of network namespaces (actually python-nemu[1]) - star topology, where all nodes runs tinc except the center, which I use to filter communications,

Question on mixed effect models with LME
Good afternoon Using R 2.9.2 on a machine running Windows XP I have a longitudinal data set, with data on schools and their test scores over a four year period. I have centered year, and run the following m1.mod1 <- lme(fixed = math_1 ~ I(year-2007.5)*TFC_, data = long, random = ~I(year-2007.5)|schoolnum, na.action = "na.omit") where

[LLVMdev] [vmkit]Errors when compiling vmkit
Hi Julien, Due to some new commits, openjdk build is broken for the moment. We are fixing this. You can temporarily use the following commit to try VMKit with OpenJDK implementation. d9bf3794d66a116999f8f16d0799fba6fe5bd822 just call the following command in your vmkit directory: git checkout d9bf3794d66a116999f8f16d0799fba6fe5bd822 Harris Bakiras On 03/18/2013 10:12 AM, Julien Pagès

Centering (e.g. on prcomp)
Hi! I'm doing a PCA on some testdata (only 2 features) currently to see what happens. I read a lot of times one should center ones data, so i left the option on. But now i am scratching my head on how to correctly transform new data to be comparable to the data used in the pca. pca$x are the points (in PC system) the function returns origpoints%*%pca$rotation is not quite the same, because

[LLVMdev] [vmkit]Errors when compiling vmkit
Hi, I see that now vmkit2 contains the last revisions of the project, so I follow these instructions to compile vmkit : http://vmkit2.gforge.inria.fr/start.php I download and compile LLVM without errors. I have tested with and without optimizations but this is the same for the errors. My configuration for LLVM is just : ./configure; make Apparently we can build vmkit with OpenJDK instead of GNU

problem with function "rep"
To whom it may concern, I am currently writing a program where I need to use function rep. The results I get are quite confusing. Given two vectors A and B, I want to replicate a[1] b[1] times, a[2] b[2] times and so on. All the entries of vector B are positive integers. My problem comes from the fact that if I sum up all the elements of B, I get a certain value x(for example 10000). And if

samba internal DNS Zone transfers and notify for slaves?
I was wondering if I can implement slave DNS servers for a samba domain. I would like to setup a slave section on my bind server that gets its information from my samba-ad dns server? Or is my only option at the moment to use bind-dlz with bind on my samba-dc? This page: https://wiki.samba.org/index.php/DNS_Administration says zone transfers is unimplemented but one of the links on there

[LLVMdev] [vmkit]Problems when modifying J3
Hi Julien, I found out what was missing for adding a field to JavaClass. While precompiling Java code (JavaAOTCompiler) we create an equivalent LLVM Constant object for each class. So modifying the internal representation of a class means that you also have to modify the AOTCompiler. Here is a patch with a tiny example where an int is added to JavaClass. If you want to add more complex

[PATCH] xen/arm: add_to_physmap_one: Avoid to map mfn 0 if an error occurs
By default, the function add_to_physmap_one set mfn to 0. Some code paths that result to an error, continue and the map the mfn 0 (valid on ARM) to the slot given by the guest. To fix the problem, return directly an error if sanity check has failed.
