MLE optimization
Folks,
I'm kind of newbie in R, but with some background in Matlab and VBA
programming. Last month I was implementing a Maximum Likelihood Estimation
in Matlab, but the algorithms didn't converge. So my academic advisor
suggested using R. My problem is: estimate a mean reverting jump diffusion
parameters. I've succeeded in deriving the likelihood function (which looks
like a gaussian
