similar to: nls and factor

I want to fit the model y=a*x^b using nls; where "a" should be different for each level of a factor. What is the easiest way to fit it? Can i do it with nls? I've looked the help pages and the MASS example in page 249 but the formula is different and I don't know how to specify it for my model. Thanks, Manuel [[alternative HTML version deleted]]

I am interested in using the nonlinear forecasting techniques developed by Sugihara et al. In particular the simplex projection and the S-Map (see this website for details and reprints: http://iod.ucsd.edu/simplex/ ). I've looked through CRAN but could not find any package with functions that allow such analysis. Any pointers? Thanks, Manu

Hi, I have already re-make the patch file, based on the trunk codes in SVN respo. But I can not build the xapian, because there are many errors when building 'languages/' for stemmer. Therefore, I could not test the new patching code. Patching code can be accessed from: http://www.xunsearch.com/download/xapian-scws-1.3.x-trunk.patch Need to install SCWS first as below steps: 1.

Hi, I will probably have to design an e-mail (and other components) infrastructure for a small ISP soon (WISP). I'm doing some research to determine which components would be best to offer e-mail services to their client and allow the staff to manage accounts easily. I usually use virtual machines a lot for isolation and easy backups and migration (when a hardware node is

I have a linear model y~x1+x2 of some data where the coefficient for x1 is higher than I would have expected from theory (0.7 vs 0.88) I wondered whether this would be an artifact due to x1 and x2 being correlated despite that the variance inflation factor is not too high (1.065): I used perturbation analysis to evaluate collinearity library(perturb)

Hi all, I have this microarray large microarray data set (ALL) from which I would like to subset or extract a set of data based on a factor ($mol.biol). I looked up some example of subsetting in, picked up two commands and tried both but I got error messages as follows > testset <- subset(ALL, ALL$mol.biol %in% c("BCR/ABL","ALL1/AF4")) >> Error in

The option se.fit in predict.nls is currently ignored. Is there any other function available to calculate the error in the predictions? Thanks, Manuel ______________________________________________ LLama Gratis a cualquier PC del Mundo. Llamadas a fijos y m??viles desde 1 c??ntimo por minuto.

When I try to unlist a very large list, R is killed without any other warning: A<-as.list(as.data.frame(matrix(1:21639744,nrow=3578,ncol=6048))) with AA<-unlist(A) or AA<-c(A,recursive=TRUE) I get a R terminado (killed) and the end of the session. I think I'll need to get more RAM (now 1Gb, any other solutions welcomed) to be able to do this but, shouldn't I get a more gentle

Hi, I have IVR and when I press 1, asterisk calls my mobile phone. If my mobile phone is offline, asterisk transfers to asterisk voicemail. I'd like asterisk detects my mobile voicemail and if my mobile voicemail answers, asterisk transfers to asterisk voicemail. For that, I used AMD. So I have problems ! Asterisk detects answering machine everytime! How do I do please ? extensions.conf

I have upgraded to version 3.0.27a on ubuntu 7.10 server and now the getent command wont display the active directory users, but wbinfo will. It worked fine with 3.0.26a and I have not changed my configuration.

Hi everyone, I need some help to setup my configuration failover system. My goal is to have a redundance system using Xen + DRBD + Corosync + Pacemaker On Xen I will have one virtual machine. When this computer has network down, I will do a Live migration to the second computer. The first configuration I will need is a crossover cable, won''t I? It is really necessary? Ok, I did it. eth0

Hi Here are a few unintegrated patches, just tested against 2.2rc7: 1) NetBSD's getmntinfo uses struct statvfs while other BSD use struct statfs http://ftp.espci.fr/shadow/manu/patch-ak 2) NetBSD 5.x net_getunixcred() support. Build on NetBSD, but not tested (I am testing on NetBSD 6.0): http://ftp.espci.fr/shadow/manu/patch-src_lib_net.c 3) Increase authentication buffer size so that it

I am trying to understand how the SOM algorithm works using library(class) SOM function. I have a 1000*10 matrix and I want to be able to summarize the different types of 10-element vectors. In my real world case it is likely that most of the 1000 values are of one kind the rest of other (this is an oversimplification). Say for example: InputA<-matrix(cos(1:10),nrow=900,ncol=10,byrow=TRUE)

whoops, forgot to copy the list on it. sorry. Well, an update. I can log in to the console using any domain profiles, but, I can not access the exposed home directory through NetBeui (My Network Places/Network Neighborhood). Also, how should I configure /etc/pam.d/sshd to allow domain users to authenticate and logon through an ssh client (PuTTY?, OpenSSH?) -----Original Message----- From:
