Hi R users: I want to know if any of you had used Stata or Statgraphics. What are the advantages and disadvantages with respect to R on the following aspects? 1. Statistical functions or options for advanced experimental design (fractional, mixed models, greco-latin squares, split-plot, etc). 2. Bayesian approach to experimental design. 3. Experimental design planing options. 4. Manuals

I am trying to get a measure of how R compares in usage as a statistical platform compared to other software. I would guess it is the most widely used among statisticians at least by virtue of it being open source. But is there any study to which I can refer? By asking this list I am not exactly adopting a rigorous approach! Best wishes John John Logsdon

Hi, I am trying to estimate a quantile regression using panel data. I am trying to use the model that is described in Dr. Koenker's article. So I use the code the that is posted in the following link: http://www.econ.uiuc.edu/~roger/research/panel/rq.fit.panel.R How to estimate the panel data quantile regression if the regression contains no constant term? I tried to change the code of

Dear all, There have been a variety of discussions on the R list regarding the use of R in clinical trials. The following post from the STATA list provides an interesting opinion regarding why SAS remains so popular in this arena: http://www.stata.com/statalist/archive/2008-01/msg00098.html Regards, -Cody Hamilton

Dear R-list, I am currently working on a dataset with a colleague who uses stata. We fit a random intercept model to the data (decisions clustered in participants) and get closely the same results in stata (using xtreg re) and R (using the lme4 or multilevel package). Now in stata, there is an additional option for the regression to control for clustering; the vce(cluster clustvar) option,

Hello, I am trying to run R-gnome on my Debian distro (Ubuntu 6.06), but something strange is happening. Inspite of having apperently sucessfully installed Rgnome 2.3.0 I keep getting the error message below, saying that Rgnome is not found. I have actually checked the folder and Rgnome is not being properly installed. I ran into this problem on both my 32 and 64 bits intallation of Debian. Any
