I would like to know if there is a way to test no correlaction in time series ? cov(r_t, r_t-1)=0 And r_t are homoscedastik and independent. Thanks [[alternative HTML version deleted]]

Dear R Users, Here is another probelm/question. I would like to run some panel regressions with R. Therefore I have combined several time periods of data for different individuals in my database. I have already run pooled OLS but I would need to calculate a Fixed Effects Estimator (within estimator). Unfortunately I couldn't find anything like that in the RSearch and I suppose that lme

Dears members of R list, It would like that a more experienced statician in R helped me to complete the analysis to follow: r = gl(3, 8, label = c('r1', 'r2', 'r3')) e = rep(gl(2, 4, label = c('e1', 'e2')), 3) y = c(26.2, 26.0, 25.0, 25.4, 24.8, 24.6, 26.7, 25.2, 25.7, 26.3, 25.1, 26.4, 19.6, 21.1, 19.0, 18.6, 22.8, 19.4, 18.8, 19.2, 19.8, 21.4,

Morning Folks, should I prefer NFS with UCARP or native GlusterFS mounts for serving the system images to XCP? Which one performes better over 1G network links? NFS is probaby easier to setup due to existing tools like rpcinfo and showmount, both are used inside the storage container code, and there is some code for NFS, not for GlusterFS, except I write one. UCARP has the disadvantage that

Hi All, I have a very simple problem. I have several files in a same directory. I would like to send for an object only the files that finish in ".sens.". I execute the command below, files <- dir(pattern="*.sens") but it includes all of the files that have "sens", independent of they be in the end or in the middle of the name of the file. How could I solve

Hi, I'm trying to use the function "error.bars", but the program don't find it, and I dont't found any package with this function. Is there some another functin to draw barplots with error bars?

It seems that MASS suggest to judge on the basis of sum(residuals(mode,type="pearson"))/df.residual(mode). My question: Is there any rule of thumb of the cutpoiont value? The paper "On the Use of Corrections for Overdispersion" suggests overdispersion exists if the deviance is at least twice the number of degrees of freedom. Are there any further hints? Thanks. -- Ronggui

Dear All, I?m using lme to analyze a time series gene expression data. I don?t have all animals in all times, the number of animals in each time is different and I have lots of NA values. An example file can be downloaded at lbmp.fcav.unesp.br/leonardo and the code used is the following: teste<-read.table(file='example.csv',sep=',',header=T) B<-1366 library(nlme)

Hi I have 1800 response variables to regress on two factors (latitude and age), what is the script to run all response variables at once instead of writing 1800 models?

Dear all, I would like to know which is the right way to check the normality assumption for performing ANOVA. How do you check normality for the following example? I did an experiment where people had to evaluate on a 7 point scale, the degree of realism of some stimuli presented in 2 conditions. The problem is that if I check normality with the Shapiro test I get that the data are not

Dear R-community The following loops produce the error message: Error in round(x, digits) : Non-numeric argument to mathematical function after performing the outer loop 6 times Splus can execute these loops but is very much slower than R . Interestingly, if the scale-argument in the step-function is omitted R performes these loops a few times more. What could be the reason for that error? Any

Hi R helpers! I have a question. I'm trying to create a function for an exercise. Here are the arguments I should include: x and y are numeric z is a name ("plus","minus","multiply","divide") and swap is logical. Here is what the function should do: When z="plus", then x+y is performed and so on for the other z names. It should give a NA

Hi All, This is my first post here. I need to use a proprietary program designed only for nt 4 or win2k. I set all things in winecfg to win2000. After, I install the program and, at the end, I choose "I will restart my computer later". The setup finished the instalaltion well with out any error message. Then, I run wineboot. No error messages again. But, I was unable to start the
