Egarch (1,1) with Student t distribution in RExcel
Hi I want to implement Egarch (1,1) with t distribution model using RExcel and VBA. May I know the syntax. Following is the code that I 'm using. rinterface.RRun "spec=ugarchspec(variance.model=list(model=(eGARCH),garchOrder=c(1,1)), mean.model=list(armaOrder=c(1,1), arfima=FALSE), distribution.model=(std))" rinterface.RRun "fit = ugarchfit(Data = b, spec = spec)"

r documentation rugarch egarch
Hi, I`m about to switch from STATA to R and have serious troubles to find proper documentations on the internet. Right now I try to find a proper documentation of the eGARCH model being part of the rugarch package. Neither here http://cran.r-project.org/web/packages/rugarch/vignettes/Introduction_to_the_rugarch_package.pdf nor here http://cran.r-project.org/web/packages/rugarch/rugarch.pdf could

rugarch: GARCH with Johnson Su innovations
Hey, I'm trying to implement a GARCH model with Johnson-Su innovations in order to simulate returns of financial asset. The model should look like this: r_t = alpha + lambda*sqrt(h_t) + sqrt(h_t)*epsilon_t h_t = alpha0 + alpha1*epsilon_(t-1)^2 + beta1 * h_(t-1). Alpha refers to a risk-free return, lambda to the risk-premium. I've implemented it like this: #specification of the model

Help with ugarchspec function
Hi I am using the ugarchspec function from the rgarch package to fit a mean variance model jointly. Following is the code I'm using: > spec = ugarchspec(variance.model = list(model="eGARCH", garchOrder=c(1,1)), mean.model = list(armaOrder=c(1,1))) On doing this, I get the following error: Error in ugarchspec(variance.model = list(model = "eGARCH", garchOrder = c(1,

Estimating EGARCH processes with R
Hallo, I am a student specializing statistics and econometrics in germany. I know there is a way to program EGARCH-processes (time series analyses) in R. If you are ackquainted with statistics already you know that there is nothing but a theorethical use of GARCH-Package in R. Not only because the distribution is gaussian, but also because the skewdness and leptokurthosis are not quite good

Install the rugarch-package
Hi, i am unable to install the rugarch package. More than that i do not even find this package in my list of possible packages. Its possible than the name has changed, or the package is not longer availiable? Is there a similar package avaliable for garch modelling except the fGarch what i am using now? many Thanks Roland -- View this message in context:

DCC model simulation in R
Hi, I have used R rmgarch package to implement EGARCH ADCC model from which I can extract conditional covariance matrix. Now I would like to introduce positive and/or negative shocks to see the asymmetric response of covariance. I have come to know that impulse response function (IRF) or volatility IRF is not compatible for any asymmetric models, therefore, the only way to introduce shocks into

run EGARCH package on REXCEl
Hi, I have limited experience on R and recently started using REXcel. Although I have been able to run both simple functions (like mean etc) and some complex ones (like Principal Component analysis, PCA) using RExcel, I am facing some problems while running EGARCH model. For this I have downloaded the 'betategarch' package for R to run EGARCH with student t dist. Although the package has

Does R have EGARCH modeling function?
I've downloaded fSeries, but looks like it just has an interface to OX(TM) Garch Modeling Software,and that OX(TM) software package is not free. So where can I find an EGARCH function that is truely usable? Thanks a lot! [[alternative HTML version deleted]]

Data
Hey everybody, i am using the rugarch-package and its great! I have a pretty easy problem, but i just dont get it, so thanks if you can help me. Normally i use: / data(DATANAME) spec = ugarchspec() fit = ugarchfit(data = x[,1], spec = spec) fit slotNames(fit) names(fit at fit) coef(fit) infocriteria(fit) likelihood(fit) nyblom(fit) signbias(fit) head(as.data.frame(fit)) head(sigma(fit))

rugarch package: VaRTest()
Dear all, I want to backtest my Value at Risk output using the VaRTest() function in the rugarch package. I do not understand if the numeric vector of VaR which needs to be calculated is in negative or positive terms. Usually VaR is expressed in positive terms. Do I have to use positive values for VaR in the VaRTest() formula? Thanks for your help. [[alternative HTML version deleted]]

look at the underlying source code
hi someone can show me how can i get the source code of a function. Is a S4 class or Method. (I'm not an expert in R environment) Exactly, Function "ugarchsim" from library (rugarch). I need to know (in detailed ) how the variance and mean ecuation of a arma/garch process are calculated. With other packages like "fGarch" i used to invoked the function debug () and allows
