similar to: Goodness of fit in quantile regression

Hi, I am trying to estimate a quantile regression using panel data. I am trying to use the model that is described in Dr. Koenker's article. So I use the code the that is posted in the following link: http://www.econ.uiuc.edu/~roger/research/panel/rq.fit.panel.R While this code run perfectly, it does not work for my data providing a warning message: In rq.fit.sfn(D, y, rhs = a) : tiny

Hello, R appears to assume that Windows drives have short file names (SFN, 8.3) enabled; for example, that "C:/Program Files/..." is addressable as "C:/Progra~1/...". Newer versions of Windows have SFN disabled on non-OS drives, however. This means that if you install R on a non-OS drive, you - can't start R.exe from the command line. - consequently, anything that

Dear all, I am running a quantile estimation with Sparse matrix and when I run the procedure rq.fit.sfn I receive the following warning: tiny diagonals replaced with Inf when calling blkfct. Does anyone knows exactly what does it mean? What's this kind of error? Should I get worried about this message? The matrix I use is a full rank matrix (and indeed I do not have any message about

This has now been mostly fixed in R-devel. What remains to be resolved is that some packages with custom make files cannot be installed from source (when R is installed into a directory with space in its name and short file names are not available) Tomas On 10/17/2017 10:37 AM, Tomas Kalibera wrote: > Hi Zach, > > thanks for the report, I can reproduce the problem and confirm it is

For what it's worth, the Windows installers for other programming language runtimes often install outside of Program Files, so at least there is 'prior art' to motivate having R install directly into the root of the home drive: - ActiveState Perl installs directly C:/Perl; - Python installs (when installing for all users) into C:/Python$VERSION; - The Ruby installers at

Dear Dimitris, I have exactly the same problem than you, Do you get some solution?

I?m trying to pull data from one table (batting) in the Lahman Baseball database. Notice X2B for doubles and X3B for triples ? fourth and fifth from the right. The dbGetQuery function runs fine when I leave there two out but I get error messages (in red) when I include 2B/3B or X2B/X3B. Can anyone give me some direction? Thanks, Philip Heinrich

All - Does anyone know if there is a method to calculate a goodness-of-fit statistic for quantile regressions with package quantreg? Specifically, I'm wondering if anyone has implemented the goodness-of-fit process developed by Koenker and Machado (1999) for R? Though I have used package quantreg in the past, I may have overlooked this function, if it is included. Citation: Koenker, R. and

Hi, how to measure the goodness of fit, when using the rq() function of quantreg? I need something like an R^2 for quantile regression, a single number which tells me if the fit of the whole quantile process (not only for a single quantile) is o.k. or not. Is it possible to compare the (conditional) quantile process with the (unconditional) empirical distribution function? Perhaps with a Chi^2

An update on this. Writing R Extensions does not recommend to have a space character in R_HOME. This means that on Windows one either should have SFN enabled (which is still the common case), or install into a directory that does not have a space in its name (so specifically not into "Program Files"). This recommendation unfortunately needs to stay for now. WRE recommends that

Hi Zach, thanks for the report, I can reproduce the problem and confirm it is a bug in R and will be fixed. Hopefully it only impacts few users now. The workaround is to create the short name for the directory where R is installed, using "fsutil file setshortname" (for all elements of the path that contain space in their name). One can revert this by setting the shortname to an

I wanted a data frame component to be named "next", for example: > m <- data.frame (matrix (0, nrow=2, ncol=2)) > names (m) <- c("prev", "next") > m prev next 1 0 0 2 0 0 But "next" being reserved prevents $ indexing without quotes: > m$next Error: syntax error > m$"next" [1] 0 0 Although they are mostly

The double quotes are required by SQL if a name is not of the form letter-followed-by-any-number-of-letters-or-numbers or if the name is a SQL keyword like 'where' or 'select'. If you are doing this from a function, you may as well quote all the names. -Bill On Fri, Oct 2, 2020 at 6:18 PM Philip <herd_dog at cox.net> wrote: > The \?2B\? worked. Have no idea why. Can

I am new to generalized linear models and studying McCullagh & Nelder (1989). Especially, I have a problem resembling the \"cheese taste\" example (5.3.1. p. 109) of the book. I tried to analyse the cheese example with R but failed to do so because R allowed me to use logit link function only with binary family that supposes 0 <= y <= 1. Do I need to scale the y\'s or

Hi. This is bug report and simultaneously urgent asking for help. I am trying to write my rsync wrapper script, which will create minutely snapshots of my data using --link-dest. I want this script to be robust, it should work even if I do suspend/hibernate/reboot without notifying the script about this actions, it should work if I make hard-reset of the computer and if I disconnect network. Also

Hello, This is not exactly an R question, but I suspect that there is an R procedure that does what I am calling (for lack of a better name) "histogram ranking". I'm trying to evaluate a set of regression features by segregating by target class and comparing the feature histograms. My idea is that if the histograms are the same for two different classes then there is no
