Hi R community I have written a loglikelihood function which I am minimizing using nlm(). nlm() is giving me no results...I mean, I am getting initial values as estimates. No iteration. I have tried many initials value close to true values and far away from tru values. But every time I am getting initial values as estimates and no iteration. Anybody can guide why this happens. Thank You
nlm() giving initials as estimates of parameters

Unlikely that someone will be interested in guessing. You are much more likely to get a constructive response if you provide the minimal reproducible example requested in the footer. Of course, it is possible that you just might find the answer if you carefully read the help page for nlm, since I don't think it matches your description of your problem.
