http://r.789695.n4.nabble.com/file/n3031344/RSV.Rdata RSV.Rdata I want to split my dataset to training set and test set using kennard-stone(KS) algorithm, it is lucky there is R packages soil.spec to implement it. but when I used it to my dataset, it does not work, who can help me, how reasons is it, below, it is my code, and my data in the attachment. ks<-ken.sto(x,per="TRUE",per.n=0.3,va="FALSE",sav=&qu...

Hi all, Can you help me change my Kennard-Stone algorithm to faster one? [The original code can run fast in matlab, but when I change matlab code to R code, it is so slow.] Since my code so crude and too many loops (changed from matlab code), it is too slow. I hope that you can help to improve the performance. Thanks. kevin ##########...

Ok, I just thought I'd publicly pat Adrian Kennard (revk) on the back for this application. This is an excellent contribution and gets my vote for app of the year. For those that aren't aware app_sms allows you to send/receive fixed line sms messages from asterisk. ( you can take a look at a quick page showing this http://www.automated.it/aste...

...ssary. Connecting Nagios to the same system, could also send sms, if something on our servers goes wrong. I also want the system to be able, that of course more than one caller can be handled at the same time. I know that Asterisk can handel this, but does "sms via fixed line" by Adrian Kennard work, using VoDSL?? And what other hardware do I need (except for the server with digium cards) to get this idea running?? As externals I'm planning to use 1 analog phone and maybe 2 headstets for each of us if we are in office. thx, Sascha

hi all a technical question for those bright statisticians. my question involves ridge regression. definition: n=sample size of a data set X is the matrix of data with , say p variables Y is the y matrix i.e the response variable Z(i,j) = ( X(i,j)- xbar(j) / [ (n-1)^0.5* std(x(j))] Y_new(i)=( Y(i)- ybar(j) ) / [ (n-1)^0.5* std(Y(i))] (note that i have scaled the Y matrix as well) k is

Hi All, I would like to use Kennard-Stone algorithm for splitting a dataset. > mydata <- read.csv(url("http://www.ats.ucla.edu/stat/r/dae/binary.csv ")) > library("soil.spec") > ken.sto(mydata,per.n=0.3) Error in ken.sto(mydata, per.n = 0.3) : subscript out of bounds I found that other people run int...

Dear R-programmer, I wrote an adapted implementation of the Kennard-Stone algorithm for sample selection of multivariate data (R 2.7.1 under MacBook Pro, Processor 2.2 GHz Intel Core 2 Duo, Memory 2 GB 667 MHZ DDR2 SDRAM). I used for the heart of the script three embedded loops. This makes it especially for huge datasets very slow. For a datamatrix of 1853*18...

Hello R-list, I am trying to calculate a ridge regression using first the *lm.ridge()* function from the MASS package and then applying the obtained Hoerl Kennard Baldwin (HKB) estimator as a penalty scalar to the *ols()* function provided by Frank Harrell in his Design package. It looks like this: > rrk1<-lm.ridge(lnbcpc ~ lntex + lnbeerp + lnwinep + lntemp + pop, subset(aa, Jahr>=1957 & Jahr<=1966)) > f <- ols(lnbcpc ~ lntex + lnb...

Hello, I?m trying to rsync Windows 2000 to Linux. It fail on the same file every in every try. If I delete from the source the problematic file, then it fail again after a while on other file. The file size vary etc. I install rsync on other Linux for test, and there was no problem to rsync the entire directory to this new destination. The error message on the client site is some

Hi, Can anyone point me at a url where i can learn to: 1. display the name of the ogg stream in the winamp window (is this to do with the oddcast config or with the .pls file?) 2. show a url automatically in the winamp minibrowser when the ogg stream plays <p>many thanks adam <p><p><p>Adam Hyde XS4ALL Internet B.V. mobile : + (31) 06 2903 6248 Eekholt 42 1112 XH

I subscribed to report a bug. if I rsync a directory from a PC (invoked on the PC) to a unix server through ssh, the first time all works fine, then if I do it again and there are no copys it crashes on the PC. If I touch one file on the PC so it copys at least one file then all is OK. I have the latest cygwin installed on a PC with freshly installed win2000 build 5.00.2195, and the latest

Dear All, We've been running samba successfully in our environment for some months. Last week we noticed that the list command when run from any of our linux hosts against a share on a windows host no longer works. The specifics. Windows 2000 domain with ddns, dhcp etc all fully operational. Windows 2000 sp4 file server Fedora Core 2 Linux hosts with samba 3.0.10 The Fedora hosts have a
