[R] Question with RExcel

[Ethan Brown]

It's hard to see where the problem is from this information.

I would suggest subscribing to and asking this question of the RExcel
mailing list (accessible from http://rcom.univie.ac.at/) and providing
more detail of what you're trying to do, what is going wrong, error
messages (is it R or Excel giving the error?) and so on. For all I
know, it may well not be an R issue at all but a problem somewhere in
your Excel or VBA setup.

Best,
Ethan

So, I decided to use the “arma” function from R, and the parameters are now well estimated. However, I cannot run the 2500 simulations. It can only do 46 simulations! I’ve already tried to run the program in another computer, but I’ve got the same problem.
