fixed parameters

[sama]

Im running some analysis with some neotropical frog populations, and im using a robust model and heterogeneity estimator in data type, the problem is that my female captures are low so the program estimates huge abundances (N) for the females ( like 50 000 or so) but the thing is that when i select other data types like closed captures or full estimator then the female abundance estimates are ok. The question is: can i use the N estimates from the closed captures or full estimator data types and fix them in my heterogeneity data type?
