Hi all, In the http://wiki.centos.org/FAQ/General page, there is this description: If you need to burn the images with another program (cdrecord on Linux, Nero on Windows, etc.) here is a good reference for burning ISO images: http://www.linuxiso.org/viewdoc.php/howtoburn.html The referenced site does not exist any more. Does anyone know good alternatives? Thanks, Akemi

...Thank you for the comment! Could you please advise me where I can find definitions of array expansion and storage mapping optimization? I've found the following papers that are probably related to this: [1] and [2]. However, maybe I missed something. Refs.: [1] - http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.29.5704&rep=rep1&type=pdf [2] - https://hal.archives-ouvertes.fr/hal-01257316/document -- Cheers, Roman Gareev.

Hello everyone, I wanted to ask if there is an R-package to fit the following Poisson regression model log(\lambda_{ijk}) = \phi_{i} + \alpha_{j} + \beta_{k} i=1,\cdots,N (subjects) j=0,1 (two levels) k=0,1 (two levels) treating the \phi_{i} as nuinsance parameters. Thank you very much -- -Tony [[alternative HTML version deleted]]

Ralf, Ok, thanks, I'll have a look. The paper I was referencing was http://citeseer.ist.psu.edu/viewdoc/summary?doi=10.1.1.94.668 from '90 I believe. There is also an Intel paper the expands on this for the Itanium.

R factors are the natural way to represent factors -- and should be efficient since they use small integers. But in fact, for many (but not all) operations, R factors are considerably slower than integers, or even character strings. This appears to be because whenever a factor vector is subsetted, the entire levels vector is copied. For example: > i1 <- sample(1e4,1e6,replace=T) > c1

The curve() function plots an expression in x over an interval [from,to]. I am looking for a function that would allow me to plot a parametrized curve t -> x(t) where x is a vector in 2 or 3 dimensions. For example (cos(t), sin(t)) (a2D  circle) or (cos(t), sin(t), t) (a 3D helix). It seems that neither curve(), plot(), nor persp() are helpful for that particular problem. I bet I?m not the

Hi Alberto, I have not used this myself, but I think you should be able to visit your Instruction ‘users()’. I think the name this function was given is a bit confusing, but this returns an iterator range you can iterate through to find instructions that depend on a given one. Similarly, you have the function ‘uses()’ that can be used to traverse down the DAG when instructions are still on SSA

Dear all, I am currently looking for a book about support vector machines for regression and classification and am a bit lost since they are plenty of books dealing with this subject. I am not totally new to the field and would like to get more information on that subject for later use with the e1071 <http://cran.r-project.org/web/packages/e1071/index.html> package for instance. Does

I?ve been using Frank Harrell?s rms package to do bootstrap model validation. Is it the case that the optimum penalization may still give a model which is substantially overfitted? I calculated corrected R^2, optimism in R^2, and corrected slope for various penalties for a simple example: x1 <- rnorm(45) x2 <- rnorm(45) x3 <- rnorm(45) y <- x1 + 2*x2 + rnorm(45,0,3) ols0 <- ols(y
