A comparison of model predictions from KPFM1 and KPFM2
seasonality into parameter estimates and a necessary change in the predator recruitment function of KPFM2 ... . These comparisons provide a preliminary indication that the substantial changes in the structure and ... logic of KPFM2 have not caused substantial changes in model results. In essence, KPFM1 has become a ... special case of KPFM2. KPFM2 thus offers a flexible framework with functionality that the user can opt to ...
