similar to: Problem with GARCH models in R compared to S-PLUS

Dear All, I attempted to fit a DVEC and a BEKK multivariate GARCH model, but am wondering which package to use. 1. I tried to use "rmgarch" package in R, but I couldn't find the subroutines for DVEC and BEKK. 2. I tried to find "rmgarch" package of R, which is not located on the official R site. This is the latest version I can find, where the programs were

Hi R users, Heard that I can't use multivariate GARCH model in R because R has only univariate GARCH models.... So, how can I run a multivariate GARCH model in R? Also, SPLUS has this utility...any ideas how can I use it in R? Thanks Shubha [[alternative HTML version deleted]]

Hi , Are there any multivariate GARCH package (e.g., BEKK) in R? I do see a few "projects" constructing multivariate GARCH package, but wonder if there is anyone that is ready for use. Thanks, Miao [[alternative HTML version deleted]]

Dear ALL, I use BEKK package to estimate Bivariate GARCH model. But when the results come out, there's no t-stat or p-value of the estimated coeffients. Does anyone know how to get the significance? Followings are the codes I input, >P1=data.frame(x,y) >y1=mvBEKK.est(P1) >mvBEKK.diag(y1) Anyhelp would be appreciated! Sincere, Zoe -- View this message in context:

Dear aDVISOR, Hope I am not disturbing you. Can you tell me how I can perform Multivariate Garch analysis in R.

Yes...And the dependent package is RDCOMClient. I was using R 2.2.0...The downloading process was smooth...But not in R 2.4.0...why is this so?

Hi R-Experts, I'm currently using R 2.4.0 in Windows XP. I'm trying to download data from Bloomberg using the package "RBloomberg", but it fails to install the three needed packages "zoo", "chron" and 'Rbloomberg". Moreover I am not able to find "RBloomberg" package as windows binary in CRAN site as only for MAC it's given. Please

Hi Experts, I have a problem in Dates. I have a zoo object called 'intra'. And the class of index(intra) is ("Chron" "Dates" "Time"). I need to put the index of this zoo object into a data frame. So I used, idat<-data.frame(Datetime=as.POSIXlt(index(intra),"GMT")) But I get the values of 'idat' to be: "01joulu2006

Hello, I have a rather complex problem... I will have to explain everything in detail because I cannot solve it by myself...i just ran out of ideas. So here is what I want to do: I take quotes of two indices - S&P500 and DJ. And my first 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 =

hello, I have been looking at multiple websites on GARCH and have looked at some books and I am getting contradictory models given for GARCH. If I use the GARCH function to fit my model, I am confused as to what the coefficents given refer to. For example if I fit a GARCH(1,1) model, GARCH will give me three coefficients Ao, Ai, and Bi I know Ao refers to the constant of the model. But what

Hello Following some standard textbooks on ARMA(1,1)-GARCH(1,1) (e.g. Ruey Tsay's Analysis of Financial Time Series), I try to write an R program to estimate the key parameters of an ARMA(1,1)-GARCH(1,1) model for Intel's stock returns. For some random reason, I cannot decipher what is wrong with my R program. The R package fGarch already gives me the answer, but my customized function

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

Hey Guys, i want to do a CAPM-GARCH model. I didn?t find anything posted online. (If there is something - shame on me - i didn?t find it.) My Problem: What is the difference if I let the residuals ?e? follow a garch process ? How do I do my regression analysis now? I began reading about regression analyis with heteroscedasticity, but didn?t get it. So i started programming. First

Dear R users, Could you please help me out. I am in trouble as I am unable to model graphs to explain the GARCH (1 , 1) model, the Hill estimator (of alpha), and the Pareto estimator. I just got introduce to R. I am working on a paper which must be worked from R. You look at the difficulty I had from the text below. [1] "DAX" "DAX_CAC" "DAX_CAC40"

Hi All, I,m trying to do a GARCH simulation in R 2.3.0 release in Windows XP. I've seen garchsim function but that is for garch (1,1) and ?garch gives an example for ARCH simulation. Can anyone help me how can i extend the help shown in ?garch to GARCH simulation? Please help me in this regard. Thanks, Sumanta Basak.

I have done the usual estimation of GARCH models, applied to my historical dataset (commodities futures) with a maximum likelihood function and selected the best model on the basis of information criteria such as Akaike and Bayes. Can somebody explain me please the calibration scheme for a GARCH model? I was not able to find a paper, dealing with exactly this algorithm for my case. I only
