I'll be even more tangent. Those interested in Ox, see http://www.de.ufpe.br/~cribari/ox.pdf Cheers, Francisco.

I am running R 1.2.2 under Linux. When using the function stl in the ts library, how can I save the seasonal component? What I would like was something like: library(ts) data(nottem) data.stl <- stl(nottem, "per") x <- data.stl$sea This what I get: > x NULL I would, however, like to store in x the seasonal component. Thanks in advance. Francisco. -- Francisco

Hi David, I hope all is well w/ you. Co-operation beetwen R and Ox would be most welcome. A possible problem lies in the fact that, although free for academic use, Ox is not open source. I too have been using Ox for computer-intensive programming. I also code some of my programs in C, but I always try Ox first, and in most cases it is efficient enough. For details, see

I have just upgraded from Red Hat Linux 5.2 to version 6.0 (with GNOME) on an intel box. I have also upgraded to the latest R version (0.64.1-2 rpm) and have also installed the corresponding GNOME rpm. However, I am not able to start R: [cribari at edgeworth install]$ R /usr/lib/R/bin/R.binary: error in loading shared libraries: /usr/lib/R/bin/R.binary: undefined symbol: __setfpucw [cribari at

A nice free software with a GUI-interface (which can be linked to R, BTW) is GRETL: http://gretl.sourceforge.net/ . Some people may find it useful for basic stuff.

When I try to install the R RPM under Mandrake Linux 7.1 (intel), I get the following error: [root at edgeworth programs]# rpm -ivh R-base-1.1.1-1.i386.rpm error: failed dependencies: libreadline.so.3 is needed by R-base-1.1.1-1 [root at edgeworth programs]# I do have realine installed: [root at edgeworth programs]# rpm -qa | grep readline readline-4.1-4mdk and

I am running R 1.2.1 under Mandrake Linux 7.2 (installed from RPM) and I installed a few packages using install.packages() . Now, I am trying to upgrade these packages using update.packages() but I believe I am running into some kind of error. See below. Any tips will be greatly welcome. Thanks in advance. Francisco PS: update.packages() only tries to update wle from version 0.3 to 0.4, gives

Hi I would like to start by thanking everyone that replied. Thank you for the information, and for the comments about how or why you use it and thankx for the encouragement re my talk.... Please note that I do not claim to have ellicited a reply from all users of R, this is a quick survey not a census. I have tried to break the responces down to the following categories: Where: (hopefully

OK, I am forwarding this to the r-help. In the original message I simply hit reply and I thought I send to ALL r-help list. (apparent not) also I recieved another piece of mail.....about the RNG in Splus 4.0 or later indicating it was modified and getting worse. I only have Splus 3.4 for HP. So I cannot try it. This makes the idea of using the pre-generated RN on CDROM more appealing.. Mai

Two questions: 1. inverse.gaussian is up there as one of the glm families, but do people ever use it? There is no inverse.gaussian in the R distribution family, and when I checked McCullagh & Nelder, it only appeared twice in the book (according to subject index), once in the table on p. 30 and once on p. 38 in a passing sentence. Is there a good reference on this distribution? 2. When I

Hello R-Users: I am want to use tobit regression for left censored panel/longitudinal data. Could you please provide me the name of "library" and/or "package" that will give me option of fitting tobit regression model for longitudinal data? Thank you.

I am trying to work out a bootstrapped Tobit regression model. I get the coefficients all right, but they all have standard error zero. And I am unable to figure out why. I know the coefficients are correct because that's what I get when do a Tobit (without bootstrapping). Here's my code: # Bootstrap 95% CI for Tobit regression coefficients? library(boot) library(AER) # for the Affairs

Hi, I'm trying to fit a tobit regression model to some data. When fitting the exact same data in Stata, I have no problems at all, however R won't converge. Its not a maxiters thing, since I've tried increasing this already. I need to be able to fit the model in R since there are users of the code that don't have a Stata license. The code is: require(AER) left = 3.218476 x =

I'm statistician I need help with tobit regression Is there assumption in tobit regression ? if any, what kind of that ? please help me !!

Hi all, Quick question - Which, if any, of the R packages contains procedures for running Tobit analysis? Regards, Matt --------------------------------- [[alternative HTML version deleted]]

Reposting from virt-tools mailing list: Hi! I'm facing a problem that could be triggered by some lacking of support from libvirt on Open vSwitch (or could be my mistake). I have interests in researching on virtual networks and SDN. To keep things simple, I've decided to use libvirt/virt-tools to manage VM's since my focus is on the network, instead of using a full feature system

Dear All: I need some guidance in calculating a goodness-of-fit statistic for a Tobit Regression model. To develop the Tobit regression, I used the tobit() method from the AER package, which is basically a simpler interface to the survreg() method. I've read about pseudo R2 and C-index and was wondering if there is a package that calculates this for me. Also, is there a reason to select

Dear All, we (Ott Toomet and I) would like to add functions for maximum likelihood (ML) estimations of generalized tobit models of type 2 and type 5 (*see below) in my R package for microeconomic analysis "micEcon". So far we have called these functions "tobit2( )" and "tobit5( )". Are these classifications well known? How are these functions called in other
