Hi,
I have a non-linear function of several parameters that I need to find the
numerical solutions for the maximum likelihood estimate. (The function was
derived from the likelihood function of a nested logit model developed by
McFadden in econometrics settings.) I would deeply appreciate it if someone
can point me to any S-Plus implementation of optimization procedures for
such multi-dimensional non-linear functions, or any other software
implementations.
Thanks.
