Hello, I would like to know if the following problem can be solved using the survival package in R. I would like to perform a linear regression: Z=aX + bY + c a,b,c being constants to determine (with errors) X,Y,Z being measurement vectors. X being eventually censored. This problem has not been consistently addressed in my field (astronomy), that's why I need interdisciplinarity help!

Dear Friends, I'm contributing to a paper on a new R package for a clinical (medicine, ophthalmology) audience, and part of the mission is to encourage people who might be occasional users of Excel or SPSS, to become more familiar with R. I'd really appreciate any pointers to more recent papers that describe R, it's growth (statistics on user base, number of packages, volume of help

Hi, I am trying to understand the alternative methods that are available for selecting variables in a regression without simply imposing my own bias (having "good judgement"). The methods implimented in leaps and step and stepAIC seem to fall into the general class of stepwise procedures. But these are commonly condemmed for inducing overfitting. In Hastie, Tibshirani and Friedman

A question on authorship and attribution policy for the Wiki. I originally credited Alan Bartlett for the page content on HowTos/ConfigureNewVideoCard, but he was not comfortable with that and the reference got removed in the edit process. I generally do not include my name on Wiki pages I create, but it is fairly common practice. Should there be a statement in the Guidelines covering this

http://decisionstats.com/2008/ohri/ Some time back, I had created a framework for data mining through on demand cloud computing. This is the next version- it is free to use for all, with only authorship credit back to me………….. NOTE - i DO retain authorship credit rights (even though it is a GPL framework) for free to anyone to use commercially It tries to do away with fixed server ,desktop

There's overlap but they are not the same thing. You can see whether someone is a copyright holder by referring to the license you had and whether there is any of their content remaining. But that might not

Hadley, With all due respect, I'm not sure what exactly your deliniation between author and contributor is, but from what I can tell I don't agree with it. >From the blogpost regarding your new purrr package: "Purrr wouldn?t be possible without Lionel Henry <https://github.com/lionel->.

I would like to get some idea of which R-packages are popular, and what R is used for in general. Are there any statistics available on which R packages are downloaded often, or is there something like a package-survey? Something similar to http://popcon.debian.org/ maybe? Any tips are welcome! ----- Jeroen Ooms * Dept. of Methodology and Statistics * Utrecht University Visit

There is a CRAN package licensed just as "GPL", say, XX, I want to use in a book. But I've needed to modify the package to make it do what I need for expository purposes. The package author(s) are amenable to my modifications, but probably unlikely to incorporate them into the CRAN version any time soon. Am I allowed, under GPL, to create a new version of the package, say XX2,

An example from the sos package: Its DESCRIPTION file says Author: Spencer Graves, Sundar Dorai-Raj, and Romain Francois. However, the package includes a findFn function, whose help file includes an Author(s) section, which reads, "Spencer Graves, Sundar Dorai-Raj, Romain Francois. Duncan Murdoch suggested the "???" alias for "findFn" and contributed the code for
