[R] Error message when using 'optim' for numerical maximum likelihood

2011-09-23 Thread Steven Craig
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 simul
