Dear all, I am a new user in r and I am facing some problems with the quantile regression specification. I have two matrix (mresultb and mresultx) with nrow=1000 and ncol=nsim, where I specify (let's say) nsim=10. Hence, the columns in my matrix represents each simulation of a determined variable. I need to regress each column of mresultb on mresultx. My codes are the following:

A student brought this question to me and I can't find any articles or examples that are directly on point. Suppose there are 2 ordinal logistic regression models, and one wants to set them into a simultaneous equation framework. Y1 might be a 4 category scale about how much the respondent likes the American Flag and Y2 might be how much the respondent likes the Republican Party in America.

Dear all, I need to run a simple linear regression such that: y = b0 + b1*x1 + (1-b1)*x2 + e which I know I can use: lm(y ~ I(x1 - x2) + offset(x2)). However, I also need to restrict the coefficient b1 to be between 0 and 1. Is there any way to include such restriction in the linear regression estimation? I saw suggestion related with the function Solve.QP, but I really did not understand such

Dear all, I need to extract the covariance matrix of my quantile regression estimation to use in a test. My regression is: qf2_1 <- summary(rq(wb2 ~ apv2 + vol2, tau = phi2[1]), cov = TRUE) I can extract the covaraince matrix by using: qf2_1 [3]. However, if I try to use it in the test, it does not work. I only need to transform qf2_1[3] in a matrix 3x3. I have already tried:

Dear all, I need to do a loop in R, but I am not sure the software is generating "n" times the variables I request differently. When I ask to print the last matrix created, I just can see the loop for n=1. To be more precise, supose I need to simulate 10 times one variable and I want to fit the 10 variables simulated in a matrix. I dont really know what I am doing wrong, but I just

Hi All, I observed the following in my try towards Multiparty Conferencing. I am establishing the Multiparty Conferencing through Asterisk Manager API. I have two users SIP/111 and SIP/101 of which SIP/101 is treated as leader. Following commands are used - Action: Originate Channel: SIP/111 Application: MeetMe Data: |edwx ActionID: ffe4563 When I use the above, Incoming call will

Hola, disculpen la pregunta si parece trivial, pero hay algún paquete o forma de leer archivos en formato "json"(1)? (1) JSON, acrónimo de JavaScript Object Notation, es un formato de texto ligero para el intercambio de datos. JSON es un subconjunto de la notación literal de objetos de JavaScript aunque hoy, debido a su amplia adopción como alternativa a XML, se considera un formato de

Dear all, I have just sent an email with my problem, but I think no one can see the red part, beacuse it is black. So, i am writing again the codes: rm(list=ls()) #remove almost everything in the memory set.seed(180185) nsim <- 10 mresultx <- matrix(-99, nrow=1000, ncol=nsim) mresultb <- matrix(-99, nrow=1000, ncol=nsim) N <- 200 I <- 5 taus <- c(0.480:0.520) h <-

I am having problems setting up the smbpasswd command to sync the /etc/passwd and $SAMBAHOME/private/smbasswd files. My passwd program (/usr/bin/passwd %u) doesn't seem to want to wait around for smbpasswd to send it a second password for confirmation. I am running Solaris 2.5.1 (103640-23) on an Ultra 2300 and using Samba 1.9.18p10 compiled with gcc 2.8.1. I thought that I had this running

dovecot-2.2.13 running on Solaris-10, app 5000 concurrent connections, and a pretty standard config where passdb is set up with driver = pam. We have had some situations where an auth-worker gets into a loop, the load on the server rises and the auth-master seems blocked untill finally no new imap nor pop session are accepted. A 'doveadm reload' restores normal operations. With debug

Dear all, I need to do a loop as following: #Consider a matrix: M <- matrix(1, nrow=10, ncol=20) #Matrices to store the looping results M1 <- matrix(0, nrow=10, ncol=400) h <- c(1:20/1000) #loop for (j in h){ M1 <- M/(2*j) } But this means that the first 20 columns of matrix M1 (that is, columns 1:20) should show the results of M/(2*0.001). Then, the following 20

Dear all, I sent an email on Friday asking about nlrq {quantreg}, but I haven't received any answer. I need to estimate the quantile regression estimators of a model as: y = exp(b0+x'b1+u). The model is nonlinear in parameters, although I can linearise it by using log.When I write: fitnl <- nlrq(y ~ exp(x), tau=0.5) I have the following error: Error in match.call(func, call = cll) :

Dear all, I would like to know whether any specification test for linear against nonlinear model hypothesis has been implemented in R using the quantreg package. I could read papers concerning this issue, but they haven't been implemented at R. As far as I know, we only have two specification tests in this line: anova.rq and Khmaladze.test. The first one test equality and significance of

Hi, I'm a student working on an implementation of asterisk en linux (red hat 9.0). I'm trying to register a sip softphone (XLite) en asterisk en local.

Hi all, I'm working on an implementation of VoIP en Linux. I have a Debian Suse (*.*.*.173) with an * and a X-lite client and a Red Hat 9.0 (*.*.*.172) with another softphone X-lite. Both of the softphones are registering and appear in the peers (sip show peers) with the good parameters of address and port. If I try to make a call, * receive the INVITE request and send a 404 NOT FOUND answer.

Hi everyone, I've got a linux machine (Debian & Samba 3.0) as the domain server for several W2K clients. Whenever a user logs in into any of the clients, the should receive its roaming profile from the linux server. But something is not working right. If the user already has a profile directory, it receives a local copy of the profile from the machine. And if it is the first time the user

Hello, I'm studying I. T. Science and I'm developing my final work to get my degree. I need to know about SSH (specially, SSH 2.0 protocol) so I've been studing deeply openssh-3.5 source code, because it could help me a lot to develop my work. I'm going to crypt communications between a close machine group within a bigger network. The task takes place over a Netgraph

Dear all, I am trying to compare the estimated coefficients of a quantile regression model between two different samples. It is a Wald test, but I cannot find one way to do that in R.The samples are collected conditional on a specific characteristic and I would like to test whether such characteristic indeed affect the estimators. The problem in the test anova.rq is that the response variable
