[R] Optimized Likelihoods

[Calvin L. Williams, Ph.D.]

R-Users,

I'm in the process of developing some notes on optimizing likelihoods
for a class I'm teaching next term. Can anyone offer examples showing
the optimization of a complex likelihood function that they wouldn't
mind sharing using optim(). I've adapted some of the S-plus likelihood
examplesfrom the ``Guide to Statistics" and  the Zip example from ``Statistical
Models in S". Any additional examples that people wouldn't mind sharing
would be greatly appreciated.

Cheers,
Calvin
