Hi, Can we get the code for calculating Oja median for multivariate data Thanks and Regards Rahul Agarwal Analyst Equities Quantitative Research UBS_ISC, Hyderabad On Net: 19 533 6363 [[alternative HTML version deleted]]

Hi Roger, As we know that The Oja median has (finite) breakdown point 2/n, i.e., is not robust in any reasonable sense, and is quite expensive to compute, so do we have some better methodology to compute multivariate median Rahul Agarwal Analyst Equities Quantitative Research UBS_ISC, Hyderabad On Net: 19 533 6363 [[alternative HTML version deleted]]

I discovered recently that the phrase "Oja median" produces no hits in Jonathan Baron's very valuable R search engine. I found this surprising since I've long regarded this idea as one of the more interesting notions in the multivariate robustness literature. To begin to remedy this oversight I wrote a bivariate version and then decided that writing a general p-variate version

Hello, I have compiled and installed (almost) wine 0.9.24 within Mac OS X tiger 4.8 with X11 etc installed. The wine configure and compile steps complete without a warning/hitch etc. However, when I run wine <prog> I receive the following warning message -- Wine cannot find the FreeType font library. To enable Wine to use True Type fonts please install a version of FreeType greater

Dear R experts, we are preparing an R-package to compute the Oja Median which contains some C++ code in which random numbers are needed. To generate the random numbers we use the following Mersenne-Twister implementation: // MersenneTwister.h // Mersenne Twister random number generator -- a C++ class MTRand // Based on code by Makoto Matsumoto, Takuji Nishimura, and Shawn Cokus // Richard J.

Hi all, just installed wine 0.9.24 and all works fine except the sound. If some program tries to use audio wine crashes. Sadly the debugger doesn't work (can't attach to process) so where could be the problem. Running wine under apple X11. Cheers, Patrick

Dear R experts, I'm planning to write some kind of multivariate regression function where I would like to use a formula method. My question is if there is anywhere some detailed introduction how to program formulas in R? A bit more about what I need: I would like to start implementing a multivariate hierarchical regression model and to keep it simple in the beginning I would restrict

Hello list. I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without modifications. How did I try it? Created a (non-root) build environment (not a mock ) Installed the kernel.scr.rpm and did a rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee prep-out.log The build failed at the end: Processing files: kernel-xenU-devel-2.6.9-67.0.20.EL Checking
