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? Thanks a lot, ________________________________________ Ricardo Gon?alves Silva, M. Sc. Apoio aos Processos de Modelagem Matem?tica

Dear R-Users, How can I compute simple moving averages from a time series in R? Note that I do not want to estimate a MA model, just compute the MA's given a lenght (as excel does).

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,

NB for CSD/HSCSD and WB for UMTS/HSDPA. The UMTS/HSDPA services already provides an excellent turbo code correction. For what i know i can tell you more about corrupted packets. The BER ranges from 10^-5 to 10^-2 for CSD/HSCDS in transparent mode, and from 10^-9 to 10^-6 for UMTS/HSDPA. It depends on signal quality and if you're walking/standing or if you're in real mobility (for example

Rethinking to BER in UMTS, it seems acceptable to use speex on it do you agree? ----- Messaggio originale ----- Da: marzullo maio <marzullo63@yahoo.it> A: Jean-Marc Valin <jean-marc.valin@usherbrooke.ca> Cc: speex-dev@xiph.org Inviato: Sabato 5 maggio 2007, 23:06:40 Oggetto: Re: [Speex-dev] AMR vs Speex on wireless networks.

I am trying to connect to a samba server (hosted by a unix platform; for which I have also ftp and telnet access). I have problems with accents in filenames: when I issue the command mount -t smbfs -o 'username=oesser,password=xxxxxxxx,iocharset=iso8859-1,codepage=iso8859-1,uid=oesser,gid=oesser,dmask=700,fmask=700' //nestor.ulb.ac.be/oesser /mnt/nestor all works fine but if I put

Hello, For basic date time arithmetics operations, AFAK, there're actually the function difftime() and the (dt + num) operations. I'm wondering if other basic operations exist, like add(dt, num, unit) where unit would be "y", "q", "m", etc. Also for the function seq.dates (or seq.POSIXt), the case for by="months" would be more useful if it

A nightly scripted rsync backup job is giving me this error WARNING: vm/escDebLenny14G-flat.vmdk failed verification -- update discarded (will try again). I've searched the web and I think probably the problem is the source file changed during the copy. However, I haven't seen any explanations for the "will try again" part. Does it try again immediately? If so, does a
