[R] Problem with "nlm" function to minimize the negative log likelihood
Hi all I have a problem in using "nlm" function to minimize the negative log likelihood of a function in R. The problem is that it gives me the same estimated values for all the parameters, except one of them, in each iteration!! Does anyone have any ideas what may cause this mistake? Thank you [[alternative HTML version deleted]]
