Dear all, I am a statistician doing research in QSAR, building regression models where the dependent variable is a numerical expression of some chemical activity and input variables are chemical descriptors, e.g. molecular weight, number of carbon atoms, etc. I am building regression models and I am confronted with a widely a technique called Y-RANDOMIZATION for which I have difficulties in

Dear all, I am interested to calculate confidence interval for fitted values in general for non-linear regressions. Lets say we have y=f(x1,x2,..xN) where f() is a non-linear regression. I would like to calculate a confidence interval for new prediction f(a1,..,aN). I am aware of techniques for calculating confidence intervals for coeffiecients in specific non-linear regressions and with them

While a plea about struggling may seem appropriate to you, it is just as content-free as a reply telling you to use Google... and like it or not, that tit-for-tat arises due to frustration with lack of specificity as detailed by Charles. That is, if you are constructive about documenting your issue with a reproducible example and mentioning what you have tried and how it failed, you won't

For the record please re-read my original message. It is clear, concise, polite and thankful for future help. I received a reply "Google it!". Thank you! Thank you Jeff for your links. I am aware of them. However, they do not point to an R package for GP for binary classification which produces prediction intervals. It seems that r-help is not as it was before. Wish you all the

Thank you Charles Berry for your kind reply. I don't see anything wrong with the word "struggling". I have spent several hours trying various R packages like kernlab and GPfit to use GP to create a binary classification model which produces a prediction interval for each sample. I have been struggling because with all of them you may create a GP classification model but it only

I have kindly asked for help and I am sad to receive such a reply from some on the r-help list. I did google it prior to sending my request, and I could not find any R package which provides GP classification model which produces prediction intervals for each sample. I would be grateful if anybody could inform me about it. Thank you. ________________________________ From: Bert Gunter

For the record: I **was** trying to be helpful. I simply didn't know whether "I struggled" meant that the OP had done a web search; as Chuck mentioned, when I did one, I found what looked like possibly helpful hits. The OP's hostile response frankly surprised me, but I see no reason to respond in kind. Cheers, Bert Bert Gunter "The trouble with having an open mind is

Google it! "R Gaussian process model binary classification."

Hi, I am just curious why does this happen: I use Goldencheetah to analyse my run. It can call R to do further analysis. I run into interesting problem (for me at least). If I plot data using plot(d$time,d$heart.rate) everything is OK if I use plot(d$heart.rate~d$time) I got error: Error in inDL(x, as.logical(local), as.logical(now), ...) : unable to load shared object

Would you consider the following patch to eval.c to allow compatibility with RCC?

Hello! I am truing to compile an R-package having c-code. I put foo.c in src/ folder and useDynLib("foo") in NAMESPACE file. When trying R CMD check, I got an error message that shared object 'foo' is not found. Then I did R CMD SHLIB foo.c first. However, after that, I got warnings from R CMD check that there is an object file in /src folder. Even worse is if I run R CMD

Hi Experts, We encountered a weird issue after restarting the server. Seems everything working fine on the configuration side but the user?s not able to authenticate with the Samba server. Can you please help to investigate the issue? Our setup details and configuration file + error logs + service status.

I just released the version 0.8 of the GPL''s rcc-project (http://www.rcc-project.net). This project has an client/server (the RCC server can be install where you want, only the client has QoS fonctionalities) architecture that permit to manage many differents coputer in the same time thanks to the remote GTK GUI. We need dome feedback to help the project, so if you ever use it, it will be

Hello R-users I am new to R and trying to write some functions. I have problems writing functions that takes a data set as an arguement and uses variables in the data. I illustrate my problem with a small example below: sample data #------------------ visual24<-rnorm(30,3,5) visual52<-rt(30,7) dats<- data.frame(cbind(visual24,visual52)) remove(visual24, visual52)

Damjan, Glad to hear that worked for you. I don't know if the gnome people can make this very much easier. Different version of different linux distros might invoke hibernate differently. How would they know which one to map to the lid button? Also, some people might want to invoke sleep rather than hibernate. If there were system commands which were persistent over all distros and

Dear all, I will present R language and R software environment to the Statistical Society of Serbia. As I will doing it to professional statisticians it seems unneccesary to me to present them how R language works in details. I am more interested to present them with the latest facts regarding R (approximately number of users, number of add-on packages etc.) and in general why they should start

Hi, there: As you all know, correlation is not a very robust procedure. Sometimes correlation could be driven by a few outliers. There are a few ways to improve the robustness of correlation (pearson correlation), either by outlier removal procedure, or resampling technique. I am wondering if there is any R package or R code that have incorporated outlier removal or resampling procedure in
