variable selection with support vector machines (SVM)
Hello
I am using support vector machine (from package kernlab) for a classification task (with RBF-Kernel). My data has dozens of variables and I need to identify which variables contribute most to the classification performance.

Conditional Autoregressive Value at Risk (CAViaR)
Hi,
I am trying to replicate Engle and Manganelli's paper Conditional
Autoregressive Value at Risk (CAViaR) by Regression Quantiles. I have the
Matlab code which I cannot get to work as I have never used Matlab before,
does anyone know if there is the same code available to estimate the CAViaR
models in R?
Thanks,

Quantile Regression
Hi,
how is it possible to retrieve the corresponding tau value for each observed data pair (x(t) y(t), t=1,...,n) when doing a quantile regression like
rq.fit <- rq(y~x,tau=-1).
Thank you for your help.

ZFS on Caviar Blue (Hard Drive Recommendations)
Hi list,
I googled around but couldn''t find anything on whether someone has
good or bad experiences with the Caviar *Blue* drives? I saw in the

Digital Caviar Blue WD10EALS 1TB drives [1]. Does anyone have any
experience with these drives?
