-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, is it possible to do an equivalence test on paired quantitative datas in R? Is there a way to calculate sample size for such tests? I've tried to find some documentation on that subject but I was unsuccessfull. I'll be happy with any links on equivalence test. If such a test does'nt exist in R, i'll do it manually if I find a

Hi all, I am wondering whether there is a small bug in the binom.test function of the ctest library (I'm using R 1.6.0 on windows 2000, but Splus 2000 seems to have the same behaviour). Or perhaps I've misunderstood something. the command binom.test(11,100,p=0.1) and binom.test(9,100,p=0.1) give different p-values (see below). As 9 and 11 are equidistant from 10, the mean of the

Hello, I followed a howto found on samba website.

Dear R experts, Did someone implemented French Curve yet? Or can anyone point me some papers that I can follow to implement it? thanks in advance for your help. Paul

Dear everyone: I am doing a research on several stock markets. And I need to construct an Bartlett HAC covariance matrix estimator for Sigma(Cov(Y0,Yj)), j is from 0 to T. Can you tell me how to do it. Your Sincerely! Nigel Gregory 01/09/11 [[alternative HTML version deleted]]

Full_Name: Leslie Corbett Version: R 2.1.1 OS: Windows 2000 Professional Submission from: (NULL) (142.161.169.185) Every time I try to use the Bartlett.test command, I get a non-responding system. Can someone help? How to reproduce: Easiest way: 1. load Rcmdr; 2. import data set (one where you would do an ANOVA); 3. manage variables in data set (choose at least one variable as a factor). 4.

i a have transformed my data to data frame named df with only column names(no rownames).each column represnt one sample with 3 observations (in deed nrow(df)=3, and ncol(df)=92).in order to check homoskedasticity of variance of my 92 samples i do: bartlett.test(df) it work and give me a result.but i'm afread of getting false result,knowen that a call of such function require a vector of data

Hi I am trying to conduct a Bartlett test between two groups Samp 1 and Samp 2, both of which are vectors of equal length. I cant find any information on how to do this. Does the data need to be in a structured list. Thanks in advance
