problems with numerical optimisation
Dear list,
this is not a particular R question but perhaps someone can help.
I am running a maximum likelihood estimation (competing risk duration
model with unobserved heterogeneity) on 30 different datasets. The
problem is that on 2 datasets the model does not converge. I am
interested if there are any methods, based on the gradients or (an
approximation of) the hessian which helps to
