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 [[a...

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 the...

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...

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

...is it the "|" and how can I restrict the number of hierarchical levels? And how to use in this context, the data, subset, weights and na.action arguments? In case you are wondering what I plan to implement, one references for example is: Haataja, R., Larocque, D., Nevalainen, J. and Oja, H. (2009).

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
