GARCH estimation
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.

sequential sum of a vector...
Hi R,
Let,
x=1:80
I want to sum up first 8 elements of x, then again next 8 elements of x,
then again another 8 elements..... So, my new vector should look like:
c(36,100,164,228,292,356,420,484,548,612)
I used:
aggregate(x,list(rep(1:10,each=8)),sum)[-1]
or
rowsum(x,group=rep(1:10,each=8))
But without grouping, can I achieve the required? Any other ways of
doing

[1] 44 55 66
How do I know the dimensions of this list?... In other words, how many
sub-lists, sub-sub-lists etc...are there in l? How do I know this?

Transposing by a group variable
Hi R,
Can I transpose a data frame by a particular group variable?
For example:
d=data.frame(group=c(1,1,2,2,2),val=c(6,4,6,3,5))
And my output should be:
data.frame(group=c(1,2),v1=c(6,6),v2=c(4,3),v3=c(NA,5))
Many thanks,
Shubha

forecasting correlation with Garch
Hello R group,
I'm using the tseries package to forecast variance and I would like to do
the same with correlation.
I can't find any way to do that with the function garch().
