Dear User, I got the following error running a regression quantile: > rq1<-rq(dep ~ ., model=TRUE, data=exo, tau=0.5 ); > summary(rq1) Erro em rq.fit.fnb(x, y, tau = tau + h) : Error info = 75 in stepy: singular design Any hint about the problem?

Hi, I load my data set and separate it as folowing: presu <- read.table("C:/_Ricardo/Paty/qtdata_f.txt", header=TRUE, sep="\t", na.strings="NA", dec=".", strip.white=TRUE) dep<-presu[,3]; exo<-presu[,4:92]; Now, I want to use it using the wls and quantreg packages. How I change the data classes for mle and rq objects? Thanks a lot,

Dear R Users, Did someone implemented the R1 (Pseudo R-2) and likelihood ratio statistics for quantile regressions, which are some of the inference procedures for quantile regression found in Koenker and Machado (1999)? I tried the Ox version, but my dataset is too large (> 50.000) and the algorith breaks. ________________________________________ Ricardo Gonçalves Silva, M. Sc. Apoio aos

Hello, I have a several time series, which I would like to check for their best fitted Arima model (I am checking for the lowest aic value). Which lets me raise two questions: 1) is there are more efficient way, than using 6 for-loops? 2) sometimes the system cannot calculate with given parameters - is there a more efficient solution than I found? I hope, you can help me to make this

Hello, does anyone know how I would go about getting R to connect to OpenOffice's Base program (OOo's version of MS Access) such that I can retrieve data from the database and perform calculations and data analysis? I'm totally new to R and Base and I've looked at some documentation, but found only examples for R connecting to PostgreSQL and MySQL, but nothing for OOo's Base

Hi all R-Experts, I'm facing one problem in yahoo data downloading. I'm suing Windows XP, R 2.2.0, and i'm using yahoo.get.hist.quote function to download data.

I'm reading those names in R and

R-help -- I built R-2.2.1 in my own directory on a sun (solaris). Now I would like the sysadmin to move the contents to /usr/local/lib and place the binary in /usr/local/bin. No problem. However, the RHOME variable defaults to the directory from which R was built so it is not usable by anyone but me or ROOT. I would like to avoid building this again if possible. Any ideas? Thanks, Dan

Hello, I am a bit over my head on this issue. My colleagues and I are running R off of our server. We all have admin rights and prior to yesterday we all had our own libraries.
