Discussion
- We assume 11 days time between broods at reference temperature (20 C). This is about the age at birth from the Tab data set, assuming that development starts directly after the last brood has been released. We do not have any information of the actual time between broods, and it might take longer than 11 days because of a mating period, or shorter if a new brood is already developing before the last has been released.
- The estimation does converge but the routine does not stop before a large amount of steps. The resulting parameters remain similar.
