Hi all, I recently updated my to R 2.6.0 and tseries package ?tseries? version: 0.10-11. When i was using R Version 2.3.1 (2006-06-01) with tseries 'tseries' version: 0.10-7, the code > garch(dflnRCLC1) ***** ESTIMATION WITH ANALYTICAL GRADIENT ***** Call: garch(x = dflnRCLC1) Coefficient(s): a0 a1 b1 4.985e+00 1.880e-01 6.210e-14 > worked very

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 <-

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

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 ======= ==================================

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))

Hi,I try to calcualte AIC or Loglik to GARCH model,But the Packege Tseries do not deal with them.How can I calculate AIC or Loglike to GARCH Model By Packege Tseries?

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]]

Follow the example in tseries, we can simulated a GARCH(0,2), n <- 1100 a <- c(0.1, 0.5, 0.2) # ARCH(2) coefficients e <- rnorm(n) x <- double(n) x[1:2] <- rnorm(2, sd = sqrt(a[1]/(1.0-a[2]-a[3]))) for(i in 3:n) # Generate ARCH(2) process { x[i] <- e[i]*sqrt(a[1]+a[2]*x[i-1]^2+a[3]*x[i-2]^2) } x <- ts(x[101:1100]) and x is a GARCH(0,2). But, I would like to know how

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. As root with R CMD INSTALL tseries_0.10-0.tar.gz I get the following gcc-3.3 -bundle -flat_namespace -undefined suppress -L/usr/local/lib - o tseries.so arma.o bdstest.o boot.o dsumsl.o garch.o ppsum.o tsutils.o -framework vecLib -L/usr/local/lib/gcc/powerpc-apple-

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

Dear All, I have loaded package(tseries), but when I run predict.garch(...) R tells me could not find function "predict.garch", however ?predict.garch shows me something. I am confused about this. How can I forecast garch volatility? I have tried: predict(...,n.ahead=...),give me fitted value predict(...,n),give me NA,NA

Hello, I have a few questions concerning the DCC-GARCH model and its programming in R. So here is what I want to do: I take quotes of two indices - S&P500 and DJ. And the aim is to estimate coefficients of the DCC-GARCH model for them. This is how I do it: library(tseries) p1 = get.hist.quote(instrument = "^gspc",start = "2005-01-07",end =

Anyone know if there's an R package somewhere that supports estimation of a linear regression model with GARCH error process? There's a garch command in the tseries package, but unless I'm missing something it is restricted to the univariate case, i.e. you can fit a GARCH model to a single time-series but not estimate a model with GARCH errors. -- Allin Cottrell Department of

I'd like to play with ARIMA models of stock prices, but I am a complete novice. Could some kind soul explain the relationship among packages "ts", "tseries", "dse", "dse2", and "fracdiff"? Are they 'competing' products or does one depend on another? Where would be the best place for a novice to begin? Thanks for any advice. PS. I
