Generating a double-exponential jump diffusion process
Dear R Users,
Does anyone know of a package which can generate random realisations of
a double-exponential jump diffusion process with a drift ? Something
where I can specify the likelihoods of an up or a down jump, the drift
rate, and the mean size, and get back a vector of realisation of the
process (for purposes of a Monte-Carlo).
Kind regards,
Tolga

Diffusion of particles inside a sphere
Hello veryone,
I am interested in the diffusion of particles inside a sphere, and its release through a small pore on the sphere surface. Unfortunately, I have not found the way to do this in R. Could you help me?
Thank very much in advance for your help

Commit history duplicated, seeing weird diffusion activity (Was: [Diffusion] rG67c416dc9a5a: [DebugInfo] Allow spill slots in call site parameter descriptions)
I just got a Diffusion notification about a change of mine being reverted by Fangrui, but I'm not sure that's actually what happened and am confused and concerned.
My commit was "[DebugInfo] Allow spill slots in call site parameter descriptions", and it appears in the history under two hashes: 1ee84e and 67c416. The first commit contains the actual change. The second touches

blocking name diffusion within two subnets
Hello
I administrate a samba server with two network cards. This server is
visible and serve his shares succesfully on two differents subnets.
Ports 137,138 & 139 (both tcp & upd) are filtered between those two
subnets by cisco switches.
The problem is that all my computers on the first subnet are visible
from the second subnet in the network neigbourhood. Only their names are

Revision https://reviews.llvm.org/rL314025 works.
Revision https://reviews.llvm.org/rL314026 does not (404 Not Found).
At the time of this mailing, the top of trunk is at 314060.
Is this some kind of known problem with Phabricator recently?

~3 hours ago, I got a big pile of emails from Phab that I had been
expecting over the last 3 days, so I think that means it's working now. :)

Looks fixed now? Something is leaking files in /tmp on the VM, leading to
mysql disk full errors. I deleted files in /tmp, but of course this is a
temporary fix. Eventually it will fill up again. =/

diffusing GIS data in maps
Hi-
I am trying to find a way to diffuse GIS data on a European map. I have a
dataset consisting of particular locations scattered across Europe,
along with magnitude and value information. I can plot these as discrete
points with something like the following:

Error message when using 'optim' for numerical maximum likelihood
Hello All,
I am trying to estimate the parameters of a stochastic differential equation
(SDE) using quasi-maximum likelihood methods but I am having trouble with
the 'optim' function that I am using to optimise the log-likelihood
function.
After simulating the SDE I generated samples of the simulated data of
varying size (I want to see what effect adding more observations has on the

finite difference scheme for 2D differential equations
Hello everyone,
I am trying to solve 2D differential equations using finite difference
scheme in R. I have been able to work with the equations with only one
spatial dimensions but I want to extend it to the two dimensional problem.
For example i can simulate one dimensional diffusion using a code like the
following. But I want to write a similar code for,say, a two dimensional
diffusion

Problems using the 'HPloglik' function in the SDE package
Hello all,
I am trying to produce the closed-form Ait-Sahalia approximation to the
log-likelihood function of a diffusion process but the function arguments I
am passing to the function result in NaN being returned. I've checked the
'Transform','S' and 'M' functions and the problem doesn't seem to be with
these. Does anyone have any ideas why this isn't working?

counting missing values
Hello R lovers
I have written a little cute function to count the number of missing value
per row in a matrix and return the percentage of missing value
it takes a lot of time to run with a 1000 rows matrix
I'd like to know if there is a function already implemented to count the
number of occurence of a given values in a vector
For information,
here is the function

It seems like this has already been set up for all the projects except for
libunwind. Can we create a Differential repository for it as well? I'll be
happy to update its .arcconfig once that's done.

Oriented object programming
Hi all
Two questions:
- I would like to learn more on oriented object programming with R. Is
there any tutorial for that?
- Without waking up a troll, I am not very familiar with diffusion
list, I am more use to forum. On a diffusion list, how can I check if
someone already asks a question? I mean, I went on CRAN-R website, I
find the R mailing list archive. But is there a way to search

The review request will belong to a single repository, as you noticed (from
the closest .arcconfig to where the arc command was invoked).
However, when commits land, they will be imported under either one (rL for
LLVM diffs) or two (rL + rC for e.g.
