Hello,
I am trying to estimate parameters of mean reverting process with jumps given
by: dp=k(mu-p)dt+sigma*dz+Jdq where dp represents change in log of price, k is
reversion factor, mu is long run level of price, sigma is standard deviation,
and dq equals one with probability lambda if jump oc

I'm able to do the first one with something like this general example
par(mfrow=c(1,2),cex.axis=0.85,cex.lab=0.80,mai=c(1.3,1,0.5,0),las=3)
bplot<-barplot(bar.values,names.arg=cf.names,width=0.5,ylab="% Area held")
abline(h=0.3,lty=3,col="red")
I have been reading, in various sources, that a poisson distribution is
related to binomial, extending the idea to include numbers of events in a
given period of time.
In my case, the hypergeometric distribution seems more appropriate, but I
need a temporal dimension to the distribution.
I have

Dear list members,
I'd like to be able to restrict the number of pages in a lattice display to
one without having to specify explicity the number of rows and columns in
the display -- that is, having forced one page, I'd like the number of rows
and columns to be determined automatically.
For exam

Someone solved the problem of saving R-objects to a database?
These are the two varaints I've tried so far without success:
1)
ser = rawToChar(serialize(obj, NULL, ascii=TRUE))
dbSendQuery(link, paste("insert into table values(1, '",ser,"')",sep=''))
The field to save the object in the MySQL Da
Thanks, I looked into the grid package. The grid package does do a
better job of managing the plotting, but it's still re-plotting the
entire canvas whenever a modifcation is made to a plot.
I guess I should have been a little clearer with my question. Here's
a sample function.

Can you give us a simple example which produces the same behavior?

Try this:
vector[ setdiff(seq_along(vector), as.numeric(idx)) ]
where idx is your vector of indices to exclude, e.g.
idx <- 3:4
idx <- numeric(0)
idx <- NULL
The last one gets converted to numeric(0) by
as.numeric so it still works.

Hi
I have recently started using the nnet package but cannot find any
documentation other than the one page titled 'nnet {nnet}' which is
replicated several times over the internet and is found in the help file
for this package.
I would like more information on how to use the package and have sea
Hi
what
dev.cur()
If it is something like
pdf

your plot is transfered to this device not to standard windows device (if
you are on Windows), so
dev.off( )
close current device and you probably can do intended plotting again. See
Devices help page.

Hello,
I have a vector x containing letters ("a", "b" etc.). Now I want to
convert it to factor and group some letters into one common level. If I do
it by factor function, giving the same label names for all values I want
to group, it doesn't work:
> x<-letters[1:5]
> x
[1] "a" "b" "c" "d" "e"

Hi there
I have some timeseries data which I plot in a OHLC Plot. In the same
plot I'd like to have the EMA of this timeseries. I tried to add the
EMA point to OHLC with lines(), but this doesn't work. Has anyone an
idea how to handle it?
