How to replace all non-maximum values in a row with 0
Hi,
I would like to replace all the max values per row with "1" and all other
values with "0". If there are two max values, then "0" for both. Example:
from:
2 3 0 0 200
30 0 0 2 50
0 0 3 0 0
0 0 8 8 0
to:
0 0 0 0 1
0 0 0 0 1
0 0 1 0 0
0 0 0 0 0
Thanks!

Predict GARCH
hello,
i was trying to predict values for a garch, so i did:
predict(fitgarch,n.ahead = 20)
but this doesn't work. Someone can tell me how to get the 20 values ahead of a garch model.
thanks in advance

Garch in the mean
Hello,
I was wondering if anyone knew how to fit a series using a Garch-M (Garch
in the mean) model. From what I gathered from the documentation, it does
not seem to be implemented in either fGarch, fSeries, or tSeries. Perhaps
there is an option that allows this functionality. Otherwise, if it's
possible to modify an existing function I would appreciate any guidance on
how to go about

garchFit in fGarch fitted values are all the same
Dear all-
Package /fGarch/ version 2100.78 in R version 2.8.1 (2008-12-22)
running on linux 2.6.22.9-91.fc7
In trying to fit garch models in above environment. I am getting
"reasonable" fitted coefficients, but the fitObject@fitted are all the
same. This is true even for the help page example:

GARCH IN THE MEAN Model in R
Dear All,
Sorry to bother. I'd like to estimate GARCH-M( GARCH IN THE MEAN) model. And
find that a package called rgarch could help. But I always can't instal
rgarch package successfully. I posted my problems and got some suggestions
but still failed. Does any one knows other method that could do GARCH-M
model?
I appreciate your time and help!
Cheers,
Xi

Length problem
Hi all
I have this problem:
In my database .dta, called "data" I have five rows
data<-read.dta("C:\\2_CO_mmobile_ALL_Rid.dta")
# From this database I wuold like to create another
coppie<-c(data[4:length(data)])
but I find this
# Length of original data
length(data[,4])
5 RIGHT!!
# Length of new data

Multivariate GARCH model in R
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

multivariate Stochastic Volatility and GARCH
Dear everyone,
i`m a german economics student, writing my master´s thesis about
"Multivariate Volatility Models". After having read about theoretical
aspects of Multivariate GARCH ans Stochastic Volatility Models, I would like
to compare DCC-GARCH and DC-SV with help of an empirical application. I
figuered out that one has to use MCMC-simulation-methods for that. Some days

Are there multivariate GARCH packages in R?
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

About multivariate GARCH: DVEC and BEKK
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

I need help with the mean equation in rgarch package
Dear R users,
I hope this email finds you well,
My name is Mariam and I am currently using R in my thesis
project. I is about modeling investors' sentiment.
My R skills are very modest and I am trying to solve a Garch in mean
equation using the "rgarch" package.
The main issue I am facing is with the mean equation, and I need a
code for it or a lead on how to edit already existing

I have a rather complex problem... I will have to explain everything in

here is what I want to do:

GARCH SIMULATION
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,

GARCH-like
I need to change the code of Garch to the FCGARCH (a non-linear
multi-regime GARCH).
I don't know nothing about R.
I'd like to know how can I get the code of the garch in order to change it
and make the fit for the FC-GARCH.
Any non-linear code will be helpfull because if doesn't help in the
programming it helps in getting familiar with R.
Thank you
Renato
