similar to: Oja median

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]]

Rahul Agarwal Analyst Equities Quantitative Research UBS_ISC, Hyderabad On Net: 19 533 6363 hi let me explain you the problem we have a database which is in this format Stocks 30-Jan-08 28-Feb-08 31-Mar-08 30-Apr-08 a 1.00 3.00 7.00 3.00 b 2.00 4.00 4.00 7.00 c 3.00 8.00 655.00 3.00 d 4.00 23.00 4.00 5.00 e 5.00 78.00 6.00 5.00 and we have a query

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

Dear all, I would like to aggregate a data frame (consisting of 2 columns - one for the bins, say factors, and one for the values) along bins and quantiles within the bins. I have tried aggregate(data.frame$values, list(bin = data.frame $bin,Quantile=cut2(data.frame$bin,g=10)),sum) but then the quantiles apply to the population as a whole and not the individual bins. Upon this

Could somebody share some tips on implementing multivariate integration and partial differentiation in R? For example, for a trivariate joint distribution (cumulative density function) of F(x,y,z), how to differentiate with respect to x and get the bivariate distribution (probability density function) of f(y,z). Or integrate f(x,y,z) with respect to x to get bivariate distribution of (y,z). Your

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.

---Adding llvm-dev list to CC--- Hi Alberto, Thanks for your prompt reply. Actually, I need this information(about total allocation size and object structure) on runtime, so that is why I was planning to encode this info and store it in the memory itself.

Hi, I have a question about exporting interactive 3D plots. I use the following code to plot a contour of a trivariate normal distribution: library(mvtnorm) library(rgl) library(misc3d) n=25 x=seq(-3,3,length=n) X=cbind(rep(x,each=n**2),rep(rep(x,each=n),n),rep(x,n**2)) p=array(dmvnorm(X,sigma=diag(3)*0.5+0.5),c(n,n,n)) contour3d(p,x,x,x,level=mean(p)) lim=c(-3,3)

Hi guys, I have configured Samba share drives on my CentOS 7 VSI, and using OpenVPN client for the users to access these shares from Windows or MAC. While I am trying to upload/download heavy files (>500MB) it is very slow in speed. Any suggestions? Thanks, Shobhit Agarwal -- Regards, Shobhit Agarwal +61-406528285

Dear All, Sorry to trouble again..... After go through www.lartc.org I have implemented the HTB instead of CBQ for the same scenario.

hi guys, I am using trivariate VAR model to get 10 step ahead orthogonalized impulse response functions. I want to use rolling sample analysis on the coefficients of the irf but I have no idea how to do that. I looked through the forums but I can't seem to find any solutions. Any suggestions would be helpful. B -- View this message in context:

Hello all, In my project, I need to allocate an extra 4 Bytes in every Alloca instruction. These additional bytes will be used to store the 'allocation info'(like size and structure of the allocated object etc). Instead of adding 4 bytes to the Alloca 'size' operand at every Alloca Instruction, I was thinking to make this change at the level where Alloca gets converted to machine

Hi Keith, Thanks a lot for your reply. Actually I am trying to build an application in linux & C for converting a voice file(that is WAV) to a text message. This is required for one of our voice project. So just wanted to know if there is any existing application already there in linux to do that. Otherwise I have to write my own. Now to right my own "wav to text" converter I

Hi All, As the problem faced by many other folks that rails 2.3.2 is not working with cgi, Now I want to revert to rails 2.2.2 on my shared host (bluehost ) can anybody guide me how to revert to 2.2.2. I tried the following: 1. I installed the older rails gem "gem install rails --version 2.2.2 --include-dependencies " 2. I tried to set the PATH env to my rails 2.2.2 version and also
