Dear R user, I am working with LOO. Can any one who is working with leave one out cross validation (LOO) could send me the code? Thanks in advance Alex [[alternative HTML version deleted]]

I have two ideas about it. 1- i) Entering variables in quadratic form is done with the command I (variable ^ 2) - plsr (octane ~ NIR + I (nir ^ 2), ncomp = 10, data = gasTrain, validation = "LOO" You could also use a new variable NIR_sq <- (NIR) ^ 2 ii) To insert a square variable, use syntax I (x ^ 2) - it is very important to insert I before the parentheses. iii) If you want to

I'm reposting this problem (perhaps a bug) now I've got more information on it. This is another point of view of the situation and I hope someone could have run into the same trouble before (and solved it :-)) This is it: * with ntbackup 2000 I create a 22Gb .bkf file in the windows machine. * I can copy that file over a samba share and get correct info form the file in windows

?? If I haven't misunderstood, they are completely different! 1) NIR must be a matrix, or poly(NIR,...) will fail. 2) Due to the previously identified bug in poly, degree must be explicitly given as poly(NIR, degree =2,raw = TRUE). Now consider the following example: > df <-matrix(runif(60),ncol=3) > y <- runif(20) > mdl1 <-lm(y~df*I(df^2)) > mdl2

Hi Folks, I am wanting advise on a good soft-phone on Linux. I have looked at Gnophone but cannot seem to get it to compile under debian sarge. I am now looing at sipXphone seem to be picking up that it is not that stable, but perhaps someone here can advise on what softphone I can use on Linux. Thanks in advance, Hamish ------------------------------------------------------------------- |

Sorry about the one-man thread but if someone would slap me... floor0_forward is declared "int". It returns "val". "val" is declared "long". "val" is assigned the return from "rint" which is "double". Am I misreading this? ber --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage:

Hello, I am trying to compile a file .Rd into .html using R CMD Rdconv -t=html /file.rd/>/file.html./ It seems that the process works ok but instead of having for example loo.cv(NMRTools) at the top of the html file I have loo.cv{unknown}. Any ideas on how to solve this? Best, Dani // -- Daniel Valverde Saub? Grup de Biologia Molecular de Llevats Facultat de Veterin?ria de la

Hi All, I have been trying to get this LOO-Cross Validation method to work on R for the past 3 weeks but have had no luck. I am hoping someone would kindly help me. Essentially I want to code the LOO-Cross Validation for the 'Local Constant' and 'Local Linear' constant estimators. I want to find optimal h, bandwidth. Thank you very much! -M -- View this message in context:

While doing pls I found the following problem > BHPLS1 <- plsr(GroupingList ~ PCIList, ncomp = 10, data = PLSdata, jackknife = >FALSE, validation = "LOO") when not enabling jackknife the command works fine, but when trying to enable jackknife i get the following error. >BHPLS1 <- plsr(GroupingList ~ PCIList, ncomp = 10, data = PLSdata, jackknife = >TRUE,

I have been using samba 2.2.2 for quit awhile running with security= share in my company. I looked into the /var/lock/samba and found a growing file unexpected.tdb. Is there a way to trim it down while samba is running or do I have to start and stop samba? Is this an expected behavior? TIA Joseph Loo

I am trying to implement a simple r-svm example using the iris data (only two of the classes are taken and data is within the code). I am running into some errors. I am not an expert on svm's. If any one has used it, I would appreciate their help. I am appending the code below. Thanks../Murli ####################################################### ### R-code for R-SVM ### use leave-one-out

poly(NIR, degree = 2) will work if NIR is a matrix, not a data.frame. The degree argument apparently *must* be explicitly named if NIR is not a numeric vector. AFAICS, this is unclear or unstated in ?poly. -- Bert Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into it." -- Opus (aka Berkeley Breathed in his "Bloom

Dear all, I am using the pls package of R to perform partial least square on a set of multivariate data. Instead of fitting a linear model, I want to fit my data with a quadratic function with interaction terms. But I am not sure how. I will use an example to illustrate my problem: Following the example in the PLS manual: ## Read data data(gasoline) gasTrain <- gasoline[1:50,] ## Perform

AFAICS, this is unclear or unstated in ?poly. I still get the same error with: library(pld) data(gasoline) gasTrain <-

Hi I am attempting to use plsr which is part of the pls package in r. I amconducting analysis on datasets to identify which proteins/peptides are responsible for the variance between sample groups (Biomarker Spoting) in a multivariate fashion. I have a dataset in R called "FullDataListTrans". as you can see below the structure of the data is 40 different rows representing a

I just want to set up a folder on my Linux 7.2 running samba 2.2.1a-4. I have looked at the smb.conf over and over. Cannot find out why my share is not showing up. I just want users on my domain to browse the network and read the folder. I am on an NT domain and the furthest i got was seeing the workgroup testgrp on my network neighborhood. But when i click on the workgroup i get an access

I'm running RH7.1 and Samba 2.2.2 . I would like to offer a VFAT partition on the server hard drive for universal read-write access. I mount the partition in fstab with /dev.hda5 /sys vfat defaults,rw,uid=1001,gid=1001 0 0 It mounts fine and shows up on the Windows 98 machine and can be opened. I can't write to it however. User and group 1001 are smbuser account, and they
