I am modelling data in the multi state open robust design, where I have one unobservable and one observable state. However, my survival estimates are confounded with the transition probabilities.

In this project survival estimates are importnat, but transition would be useful but is not necessary. My question is if I set transition probabilities to equal 0, the same as the p, pent parameters for the unobservable state, what am I saying about the population in the model?

Does it just mean that transition is not being modelled? Or am I saying that there is no transition at all? As I need it to be modelled for animals to be emmigrating and immigrating.

Thanks
