| Thread-topic: | Help using the optim() procedure |
I am trying to use the optim() procedure to perform a Nelder-Mead optimization but I need to have a minimum constraint for my parameters to be greater than zero. Has anyone encountered this before -- Do you know how to get the optim() command to do this? Thanks |
