similar to: Nonliner Rgression using Neural Nnetworks

Dear List, I am trying to solve a problem by the neural network method(library: nnet). The problem is to express Weight in terms of Age , Sex and Height for twenty people. The data frame consists of 20 observations with four variables: Sex, Age, Height and Weight. Sex is treated as a factor, Age and Weight are variables normalized to unity, as usual. I wanted to construct a neural network, and so

Hi R users! One thing I cannot understand with R is the frequently appearing " Correlation of coefficients". I do not find a through going explanation of this concept either on the help pages of R or on the internet. A Google search has shown many examples of R/S-Plus outputs but no explanations of meaning. I am afraid this turns out to be a silly and unworthy question. Would anyone be

Dear R users, I have a data set of 25 cases with 150-160 explanatory variables(the number of which depends on what I choose from 200 odd digitalized spectrum strength numbers) and one dependent variable(a sensory test result). My natural choice is to work on a principal component analysis using the explanatory variables, thus enabling to characterize and describe the data space, and make a

Hello. I''ve just started with Xen and configuring Dom0. My hardware is Core2Duo based Xeon server and I installed Debian etch for amd64 architecture. The Xen related pachages installed are the following. linux-image-2.6.17-2-xen-amd64 linux-modules-2.6.17-2-xen-amd64 xen-hypervisor-3.0.3-1-amd64 xen-tools xen-utils-3.0.3-1 xen-utils-common My problem is that when xend is

Hi all I want to construct a generalised nonlinear model (binomial family) using gnm, of the form: Response = a + b variable1 + c variable2 + d variable3 - d b variable4 - d c variable5, with the parameters b, c, and d appearing more than once. Hence, I think I need to use a custom nonlin function with gnm. One of my predictor variables is categorical, so I have created a dummy variable for

Dear friends, I'm stuck with the following problem: I would like to do a multiple regression with muliple dependent variables, and i don't know how to write my formula in the model. Someone in previous messages offered the cbind method, but the result is just as many regression as the number of dependent variables, it is just a time saving method; i'm looking for a method closer to a

Hi, I'm having problems with libvirt crashing after a couple hours when a specific domain monitoring program is running. I have pasted below the following: 1. libvirt version 2. qemu-kvm version 3. OS version 4. Kernel version 5. libvirt status post-crash 6. libvirtd.log (info level dump around crash; too long to post everything so just the beginning and end. UTC) 7. custom.log (on what

Hi, I'm trying to get the so-called "single instance store" (I think cyrus has got the name for the first time) with dovecot --version = 2.0.19 binary package installed from ubuntu 12.04 lts official repo. I have checked that "maildir_copy_with_hardlinks" is enabled ("dovecot -a|grep hard" shows "yes") then I have installed and enabled the lmtp

I recently built R-devel on Windows XP (sessionInfo below), and when loading libraries that require the iconv.dll was getting an error stating that 'This application has failed to start because iconv.dll was not found. Re-installing the application may fix this problem.'. An R-2.8.1 that I installed using the Windows installer has this dll in R-2.8.1/bin, whereas in R-devel it is still in

Hi list, I downloaded and tried to install Mongrel (latest stable version) from the -win32 gem. Platform is Win2K. It said it needed daemons so got and installed that. Then it said it needed cgi_multipart_eol_fix (I think that was the name, not at my machine now, can confirm later and repost if needed). Googled for that but couldn''t find it. (Don''t have net connectivitity for a

Hello everyone ! I will buy a new PC for CentOS 5.0. I install Linux on PC for the first time. I do not have the skill of it. Here are my candidates of mabo : Intel DG965WH Intel DG965YCK Intel DG965WHMKR ASUS P5B-V All mabos have Intel G965 chipset + ICH8 Did anyone succeed to install CentOS 5.0 on these mabos, and to set up network configuration ? Could you give me any information about

Hi all, Thanks to Dr Paul Murrell in New Zealand to remind me of security consideration. I am releasing version 0.2 with security fix. This version will allow you to add banned R function names in a list. R_PHP_Online is a PHP CGI web interface to run R programs online, with the capability to show graphics online. You can get current version of R_PHP_Online from http://steve-chen.net/R_PHP/

Hi. Three years ago, I've read the question of availability of SOM library for R using Kohonen's SOM_PAK in this mailing-list. This answer was no availability. And no package dealing with SOM in CRAN. Is this situation same? Could you tell me availability this library? Best Regards.

Hi. I'd like to build installer for integrate my GUI program for R, R for win and RDCOM. Can the distribution like this be got permission? If so, installation of these softwares will be done in just one time. And where can I get each inno setup'iss file for R & RDCOM. Because these sources seem no to include their own iss file. Regards.

I just uploaded two packages to CRAN. shapefiles_0.1.tar.gz - functions to read and write ESRI shapefiles (including dbfs) emme2_0.1.tar.gz - functions to read binary data from an EMME/2 databank data (EMME/2 is a transportation modeling program) Please let me know if you find any bugs or have some suggestions. Thanks. Regards, Benjamin Stabler Transportation Planning Analysis Unit Oregon

Hello everybody!!!! Quick question, if you'd like to throw a little tip: does anyone knows a function that runs piecewise regression models with coefficients estimation and inferences ? Thank you [[alternative HTML version deleted]]
