Hi, Currently I am trying to solve a minimization problem using optim as method Nelder-Mead. However, Neldel-Mead needs many iterations until it finally converges. I have set $control.trace and $control.report such that I can see the value of the function at each iteration. I do see that I set the convergence criteria to strict in the sense that the function value does not change much. However, before loosening my convergence criteria, I was wondering how to progamm that I can see the estimates of the true parameters and of the hessian such that I can see whether they do not change much either. Than I can adjust my convergence criteria such that he ends at that point. I do know how to adjust the convergence parameters but I do not know how to obtain intermediate estimates of the parameters. I was wondering whether someone can help me with this.
Kind regards, Lisanne Sanders _________________________________________________________________ Wil jij ook onbeperkte opslagruimte?
