There have been one or two questions posted to the list regarding the optim
error "non-finite finite-difference value ." The error apparently means
that the 4th element of the gradient is non-finite. My question is what
part(s) of my program should I fiddle with in an attempt to fix it?
Starting values? Something in the log-likelihood itself? Perhaps the data
(which is generated)? Any thoughts would be greatly appreciated.
