I'm trying to maximize a likelihood with respect one parameter using "optimize" on simulated data (without error component).
I've iterated the maximization procedure 1000 times and I should always obtain the same estimate of the parameter (equal to the simulated one) but, instead, i obtain different results (the likelihood function shouldn't be flat). Does anybody has experience with the optimize procedure?
Thanks in advance,
Chiara
