Hi, What other information should i post? I now have the two versions on the same machine. With R 2.3.1 and tseries 0.10-7 it works fine. With R 2.6.0 and tseries 0.10-11 the function garch doesnt work. The test was made with the same data, in the same machine. The maintainer did not say anything yet. Regards, Jos?

Hi, I am trying to fit a GARCH(1,1) model to a financial timeseries using the 'garch' function in the tseries package. However the parameter estimates obtained sometimes match with those obtained using SAS or S-Plus (Finmetrics) and sometimes show a completely different result. I understand that this could be due to the way optimization of MLEs are done, however, I would appreciate any

I am wondering how to run 'garch' function of 'tseries' package in R2.6.1. I installed R2.3.1 and R2.6.1 in my PC (Windows XP Home) and run a following simple GARCH function in both versions: >garch(dSP[1:300], order = c(1,1)) where 'dSP' is daily return series of a stock index. R2.6.1 can not finish calculation and also I can not stop the

I was running some likelihood ratio tests (using the current version of tseries) and found a different value for the log-likelihood from what I was getting using other software. I've traced the problem to R's GARCH using the conditional standard deviations instead of the conditional variances. This amounts to a factor of 2 once logs are taken, and could easily be a case of bad

Hi all, I recently updated my to R 2.6.0 and tseries package ?tseries? version: 0.10-11.

Hello again! Is there a way to include a mean in the garch function in the library(tseries), please? I tried include.mean=T in the function statement but it didn't work thanks in advance! R Version 2.2.1 Windows Sincerely, Erin mailto: hodgess at gator.uhd.edu

Dear Sir, First of all Happy Holidays!,... I am writing to you because I am a bit confused about ARCH estimation. Is there a way to find what garch() exactly does, without the need of reading the source code (because I cannot understand it)? In Eviews (the results at the end) I am getting different results than in R (for those that have the program I do: Quick -> Estimage Equation ->

Dear R users, I am trying to use tseries' garch function in order to determine the volatility of a return series generated by quantmod. Here is the code that I am using: > library(quantmod) > getSymbols("AAPL") convert daily closing prices into continuous log returns > dret<-dailyReturn(AAPL,type='log') check to see that the autocorrelations decay >

I'm using R 2.1.1 and just successfully installed packages tseries, fseries. I try to run example http://www.maths.lth.se/help/R/.R/library/tseries/html/garch.html But it shows > x.arch <- garch(x, order = c(0,2)) # Fit ARCH(2) Error: couldn't find function "garch" Then I run command > help.search("garch") it shows the R information.

I'm having no luck getting GARCH parameter estimations. It seems simple enough, but I don't know what I'm doing. I'm a newbie both at R and GARCH models, so whatever is going wrong, it's probably very basic. Here's what I do: 1. I first load the tseries package with: library("tseries") 2. I then load the data with: g <-

Hi, there, First of all, I am not familar with the GARCH concept as well as R interface. I have three questions regarding GARCH (1,1). First, I got tseries package from CRAN. Where exactly am I supposed to install it? In my case, I copies it to C:\Program Files\R\rw2001\library. What do I need to do in order to actually install it? Second, I am not sure if I've installed it properly, but

Hi, I'm running R 2.4.1 on Fedora Core 6 and am unable to install the tseries package. I've resolved a few problems getting to this point, by running a yum update, installing the gcc-gfortran dependency, but now I'm stuck. Could someone please point me in the right direction? ========R install.packages output ======= ==================================

I upgraded to R-2.2.1 on two PPC G5 computers today. Further I want to work with the tseries package for the first time.

Dear Sirs, I am trying to perform a garch analysis to some data time series.Therefore, I've downloaded the package "tseries", as the garch analysis is not available in the main R program.When I try to load the "tseries package" from the R-Console screen, the following message appears: local({pkg <- select.list(sort(.packages(all.available = TRUE))) + if(nchar(pkg))

Hello all, I would like how to modelized a time serie with AR-ARCH process. It can be used arma and garch functions in tseries package for build ar process or a garch process, but how can it be modelized a ar-garch model ? Thanks [[alternative HTML version deleted]]
