Hi all,
in the optim() function there is no control over the size of the initial
simplex for the Nelder-Mead algorithm. Two years ago Ben Bolker
suggested to include an additional control parameter to allow more
flexibility in this respect. Did anybody implement such a modified
version.
Thanks in advance
Jens
