Dear all, For an ordinary ridge regression problem, I followed three different approaches: 1. estimate beta without any standardization 2. estimate standardized beta (standardizing X and y) and then again convert back 3. estimate beta using lm.ridge() function X<-matrix(c(1,2,9,3,2,4,7,2,3,5,9,1),4,3) y<-as.matrix(c(2,3,4,5)) n<-nrow(X) p<-ncol(X) #Without standardization

Hello, I use Gentoo and I can't get R 2.0.1 to compile. I used the portage system, Gentoo's source package sytem, and after it uncompresses the source to R, it says that I don't have a fortran compiler. It told me to use f77 flag and re-emerge gcc, which I did with the f77 and fortran flags, but it still won't compile. Does anyone have any ideas? I suspect that gcc has changed

Dear R People: Please excuse the off topic question. What are the dimensions of A-4 Paper, please? Actually, the question should read, "how do I set up a LaTex file to fix A-4 paper, please?"

After a search session in Google, I found this page: http://www.prevx.com/filenames/X1993788672854780728-0/RGUI.EXE.html which classifies Rgui.exe (clearly stated as "R for Windows GUI front-end") in a database of virus, spyware and malware! No comments! Philippe Grosjean

...o, this is also an older version of R. Get the newer sources and recompile. I don't know if Michele is still active in maintaining R for Mandrake. But he has a site for R and Mandrake in italian and this may provide some first clues. HTH, Ioannis -- Ioannis C.

Hello anyone, I'm trying to install R on Mandriva 2006 distribution via rpm file with the line urpmi R-2.0.0-1mdk.i586.rpm but I got an error message saying that the file is not accessible due to some info problem. I also tried with a source code in R-2.1.1.tar but I think that there is some problem concerning the new version of gcc (4.x), so I downgraded it to gcc 3.4.5 but it does

Dear all! Although the Psycho-Toolbox for Matlab is free software, Matlab isn't. I'm planning to do an experiment where it's essentail to travel to the subjects, not let the subjects come to where the Matlab licences are :-( So I need to use a free software for my experiment if I don't want to by an extra Matlab licence (which I don't want to). Did anyone ever try to do

Hello, My name is George Pantopoulos, i am a phd student in the Dept. of Geology, University of Patras, Greece. I am studying the statistical behaviour of bed thickness datasets taken from outcrops. Until now, 4 statistical distributions seems to fit my datasets: power law, lognormal, lognormal mixture with 2 modes and exponential. I already used the MIX package of R to detect a possible 2 mode logn...

Have you got any rough estimation about memory-MIPS requirements for the fixed point implementation? The target hardware will be a motorola style single MAC 16bit fixed point DSP. Is here any implementation of speex on DSP? Thanks G.

We are bellow 30MIPS for our 16bit single MAC fixed point DSP. 8khz/8kbps I aggree with Jean-Marc that MIPS is dependent from the target DSP, but it's a very good indication when you compare same architecture DSPs. It is very difficult (impossible) to use effecient a DSP using only c. George ----- Original Message ----- From: "Andre Borrelly" <andre@myavalaunch.com> To:
