In the optim() documentation, the control parameter "maxit" says
"There is no other stopping criteria." That should be "are", or
"criterion" ...
While I'm at it -- poking at the code a little bit, it looks as if the
initial simplex is set from the initial point by displacing each
parameter value by max(0.1,0.1*pmax(fabs(Bvec))), where Bvec is the
initial parameter set. It would be nice to have a bit more external
control of this procedure.
Is anyone interested in hacking this? If I did it myself would
anyone be interested in the results? Or does fussing with the
Nelder-Mead simplex seem silly because anyone who is really serious
about optimization will being using another method anyway?
