Garchoxfit package
Dear List,
I'm now using Ubuntu 10.10 and I want to use the garchoxfit
function.It seems that I need to download the package.
While after installing the package,I still can't use the garchoxfit
function.What's the reason and how to fix that?
Thanks for your time!

FIGARCH
Hi All,
Currently I'm working in FIGARCH process [Fractionally Integrated
Generalized Autoregressive Conditional Heteroscedasticity]. I've already
got the codes to do the process in S-Plus. Can anyone help me to do it
in R?
Thanks,

How to use S-Plus functions in R
Hi
I am very new to R. I used to work in S-Plus a lot but that was years ago.
I wrote a large number of functions that I now want to view and edit in R.
I know I have to tell R where the functions are but I have no idea how. The
functions are stored on my laptop's c-drive. I tried everything I could
find e.g. library(myfilepath), source(myfilepath) etc. but nothing seems to
work.

I want to download "garchOxFit" function.
Dear R help.
Hello.
I want to fit the model of "FIGARCH" on TimeSeries data.
So I need to use the code of "garchOxFit".
I don't know how to estimate FIGARCH model.
Please let me know which package I need and
what is procedure of estimating FIGARCH by R.
I think I need this code!

R crash after fGarch update
Hi folks!
After updating my packages my R seems to have completely crashed as will not
start up - even after I installed 2.8.1 from 2.8.0.
I get the following:
Fatal error: unable to restore saved data in .Rdata
Error in loadNamespeace(name): there is no package called fGarch
But I do have a package called fGarch.
After I hit ok, it crashes and exits. I cannot use any functionality at
all.

update win FAQ q1?
Hi,
on http://cran.at.r-project.org/bin/windows/base/rw-FAQ.html#Where-can-I-find-the-latest-version_003f
it says:
... The current release is distributed as an installer
`R-2.6.1-win32.exe' of about 30Mb. ...
however I find this file as well:
http://cran.at.r-project.org/bin/windows/base/R-2.6.2-win32.exe
I guess that in the FAQ it should read as 2.6.2
Have a nice holiday,

fGarch - Fitting and APARCH-Modell with fixed delta
Hi there,
I'm trying to fit a GJR-GARCH Model using fGarch. I wanted to try that by
fitting an APARCH model with a fixed delta of 2 and a non-fixed gamma. So I
was simply trying to use:
spec <- garchFit(~aparch(1,1),data=garchSim(),delta=2)
coef(spec)
And sometimes, it's working like a charm and delta is indeed exactly 2 in
the resulting coefficient vector.
Frequently, though, the

Methods not loaded in R-Devel vs 2.8.1
Dear list-member,
I am currently developing a package with S4 classes. The NAMESPACE and DESCRIPTION is printed below. Within this package I have set a method "residuals" for two classes. In version 2.8.1 these two are reported whereas in R-Devel (2009-01-28 r47766). What have I missed? What has changed and how can I rectify the issue? Your help and pointers are welcome.

fGarch: how to use garchFit() in loop?

How can I specify the order p,q of a GARCH(p,q) model within a loop? Here's a minimal example showing that an "Formula and data units do not match"-error appears:
library(fGarch)
spec <- garchSpec(model = list(alpha = 0.1, beta = c(0.4, 0.4)))
data <- garchSim(spec, n = 100)
x <- list()

Problem with Extracting Fitted Values from fGarch package
Good day everyone,
I fitted a GARCH model to a time series and R estimated the model and provide me with the estimates. However, when I tried to extract the fitted values from the estimated model I got the following error message:
"Error in .local(object, ...) : object "fit" not found"
I used the following to extract the fitted values

Plotting skewed normal distribution with a bar plot
Hi,
I need to create a plot (type = "h") and then overlay a skewed-normal
curve on this distribution, but I'm not finding a procedure to accomplish
this. I want to use the plot function here in order to control the bin
distributions.
I have explored the sn library and found the dsn function. dsn uses known
location, scaling and shape parameters associated with a given input

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

AIC in time series
Hi everybody,
I have fitted an ar(1),Garch(1,1) model to some observations with the
help of the garchFit function which is in the fGarch package. Here
what I've done:
library("fGarch")
fit = garchFit(formula=~ar(1)+~garch(1,1), data=garat)
Now I want to count AIC for this model. How can I do it? I cannot do
it with the AIC function of stats package, because R tells me:

a question
Dear R-helpers,
I need to read some data from output of garchFit in fGarch.
my model is garch(1,1) and i want to read
coefficients(omega,alpha,beta) and timeseries(x) and conditional
SD(s). because i need them to use in other formula.
for example :omega+x[1]+s[3]
and maybe i have several simulation then i need a general way to read
them, not to read with my eyes for example the quantity of

A mistake in garchFit()? {fGarch}
Hello,
I was using garchFit {fGarch} to fit some GARCH processes.
I noticed that the result contains "Log Likelihood" value (right above
"Description"), but when I use .. at fit$llh to retrieve Log Likelihood value,
the sign switched.
I am confused about which value I should choose to report...
Any help here?
Thanks a lot!
Ted
