Hi, I am an old hand at chemistry but a complete beginner at statistics including R computations. My question is whether you can carry out nonlinear multivariate regression analysis in R using neural networks, where the output variable can range from -Inf to + Inf., unlike discriminant analysis where the output is confined to one or zero. The library nnet seems to work only in the latter

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

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

Are you saying that when I replace the Samba server by a Windows SMB2 share server, I should see better performance? I can perfectly test that out and record a Wireshark trace for this if you like... Layperson question: Would

Matz claims 1.8.3 might be released in April. If we''re lucky, maybe it will have the Windows socket connection fix applied. (Although the patch has been hanging around since last June... but maybe they just needed some prodding. :) ) Then RubyTorrent will be much more usable on Windows. ----- Forwarded message from Yukihiro Matsumoto <matz@ruby-lang.org> ----- Date: Tue, 8 Feb

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

Ah, ok, "directory handle leases"... Ouch, I see... :-( In this case, I will first repeat my test scenario with a Windows SMB2 server and report back here. Based on the results of this exercise, you can then advise whether you still want to move this to smb-technical and raise this with Microsoft folks (who still might have a simple workaround "fix" to improve their SMB2

Hello. This is a follow by myself. I added the following lines (with + marking) to /etc/network/interfaces and problem is solved.

So, probably some of you, at least, follow Fedora, perhaps in part to see what new desktop user oriented decision will make it into the next version of RHEL/CentOS. You may have noticed how if Fedora, by some odd scheme, deems your password unworthy, you have to click Done two times. So, the latest Ananconda takes this one step further. Passwords that the system considers weak will no longer

We in the JRuby project are working to get Rails to work successfully. However, the array-indexed block parameter is not something currently supported in JRuby: x = {} [1,2].each {|x[:foo]|} This is not used extensively in the Rails code, but it''s used enough to cause things to break in JRuby. We have been modifying the above to use a temporary local variable, but obviously

Hello Jeremy, Andrew, All, I can now indeed confirm that my test scenario runs MUCH faster when executed against a Windows 10 SMB2 server than against Samba (test scenario takes ~ 18 seconds using a Windows SMB2 server as opposed to ~ 300 seconds when the server is Samba 4.6.5). But, most interestingly, the reason for these performance gains is NOT - as assumed by Jeremy - that the number of

Well fellow R users, I throw myself on your mercy. Help me, the unworthy, satisfy my employer, the ungrateful. My feeble ramblings follow... I've searched R-Help, the R Website and done a GOOGLE without success for a one way ANOVA procedure to analyse data that are both non-normal in nature and which exhibit unequal variances and unequal sample sizes across the 4 treatment levels.
