However, there is something wrong when comparing the solution provided by nlminb with the plot of the function i am trying to minimize. Nonlinear function optimisation using nlminb function in r. True, a list with the values obtained from optim or nlminb. Optim tells me it converged but nlminb tells me i get relative convergence. If you are doing univariate optimisation, it is probably worth looking at optimize. I have constructed the function mml2 below based on the likelihood function described in the minimal latex i have pasted below for anyone who wants to look at it.
