...iable and adding a variable at a time reaching a maximum of 20 variables. I get the following warning messages after my "for" loop runs. Should I be concerned about these messages? I am building predictive models and am not interested in inference. Warning messages: 1: In summary.rq(quantreg.emaff) : 3 non-positive fis <- I don't understand this message - is this a cause for concern? 2: In summary.rq(quantreg.emaff) : 3 non-positive fis 3: In summary.rq(quantreg.emaff) : 5 non-positive fis 4: In rq.fit.br(x, y, tau = tau, ...) : Solution may be nonunique 5: In summary.rq(q...

Hi all, I'm trying to load the quantreg package but keep running into problems no matter which method I have tried. Does anybody know what this error (below) means in plain language and what I might do to get this installed. I have not had problems downloading/installing/running packages in the past. thanks in advance, derek Begin R...

Dear R-help, Has anyone been able to use the quantreg package on Windows successfully? I tried to load it and get the following: > library(quantreg) Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library "C:/PROGRA~1/R/rw1031/library/quantreg/libs/quantreg.dll": LoadLibrary failure: The spec...

I was trying "quantreg" package, lm1 <- lm(y~x) rq1 <- rq(y~x) plot(summary(rq1)) #then got a warning says singular value, etc. but this line can be omited plot(lm1) #crash here It happened every time on my PC, Windows XP Pro Serv. Pack 1, Pentium(4) 3.00G. [[alternative HTML version deleted]]

Hi All, I'm still having significantly difficulty getting the quantreg library running in R. I'm running R on MEPIS using the debs created by Dirk Eddelbuettel and placed in apt testing. When I try to install quantreg using the install.packages() function it fails with: /usr/bin/ld: cannot find -lblas-3 Dirk was nice enough to send me a .deb for quantreg w...

Hi all, I'm having some troubles with the Quantreg package. I am using R version 2.10.0, and have downloaded the most recent version of Quantreg (4.44) and SparseM (0.83 - required package). However, when I try to run an analysis (e.g. fit1<-rq(y~x, tau=0.5)) I get an error message saying that the function "rq" could not be found. I...

Hi All, I'm trying to install the quantreg library on my MEPIS box (debian-based linux). When I try >install.packages("quantreg") it fails to loads and errors with: /usr/bin/ld: cannot find -lblas-3. I tried installing a ton of packages to fix the missing part but the only thing I manage to do it cause problems with anoth...

I used R and the quantreg package in a manuscript that is currently in the proofs stage. I cited both R and quantreg as suggested by citation() and noted the version of R and quantreg that I used in the main text as "All tests were computed with the R v2.9.0 statistical programming language (R Development Core 2...

I've just installed R 1.0.8 (for Windows) and I tried to install the package Quantreg directly from Cran but it's not in the list of downlodable packages. I tried also downloading the zip file and then install it but there is an error. How can I do it? Thank you [[alternative HTML version deleted]]

Hi All: I tried to download and install "quantreg" (a package for doing quantile regression) from CRAN. When I ran install.packages ("quantreg") within an R session, I got the following error message: <----Beginning of error message ---> * Installing *source* package 'quantreg' ... ** libs g77 -mieee-fp -fPIC -...

...all my files over to a new drive. I completely reinstalled R (now 2.15.2) and all my libraries to my computer (Dell Latitude running Windows 7). A few of my previous workspaces (created with R 2.14.1) can't be restored, reporting an error similar to the one I get when I try to load "quantreg" package which requires "SparseM" (see below). So, not only will "quantreg" not load but some of my workspaces can't be restored when being loaded (see below). Not sure about what this is about. I asked Roger Koenker, the package maintainer, but he is on travel...

Dear All, I'm trying to construct confidence interval for an additive quantile regression model. In the quantreg package, vignettes section: Additive Models for Conditional Quantiles http://cran.r-project.org/web/packages/quantreg/index.html It describes how to construct the intervals, it gives the covariance matrix for the full set of parameters, \theta is given by the sandwich formula V = \tau (1-\tau) (...

Dear all, I know that my question is somewhat special but I tried several times to solve the problems on my own but I am unfortunately not able to compute the following test statistic using the quantreg package. Well, here we go, I appreciate every little comment or help as I really do not know how to tell R what I want it to do^^ My situation is as follows: I have a data set containing a (dependent) vector Y and the regressor X. My aim is to check whether the two variables do not granger-cause ea...

Please, is there anyone who can give me some suggestions? (1) I have to use a package from R on my work. The package is the "quantreg" developed by Koenker (Uni Illinois). I have installed the package in the R library tree /usr/local/lib/R/ library of my Linux Operating System. I did R CMD INSTALL -l /usr/local/lib/R/ library /path/to/quantreg_x.y-z.tar.gz. However, when I call any function from quantreg, it is not recognize...

Rers: I installed R 2.9.0 from the Debian package manager on our amd64 system that currently has 6GB of RAM -- my first question is whether this installation is a true 64-bit installation (should R have access to > 4GB of RAM?) I suspect so, because I was running an rqss() (package quantreg, installed via install.packages() -- I noticed it required a compilation of the source) and watched the memory usage spike to 4.9GB (my input data contains > 500,000 samples). With this said, after 30 mins or so of processing, I got the following error: tahoe_rq <- rqss(ltbmu_4_stem...

Hi, I have used package quantreg to estimate a non-linear fit to the lowest part of my data points. It works great, by the way. But I'd like to extract the predicted values. The help for predict.qss1 indicates this: predict.qss1(object, newdata, ...) and states that newdata is a data frame describing the observations a...

Hi Folks, I've got a question regarding the 'quantreg' package maintained by Roger Koenker: I tried to produce LaTeX tables using the longtable and dcolumn options as decribed in the manual, but the function latex() doesn't seem to react on _any_ other options than 'digits' and 'transpose'. To reproduce these results the f...
