I'm working with a dataset right now that has consistently small recapture probabilities ( ~ 0.01 - 0.04). To help the optimization routine in MARK I first supply initial starting values to the mark function, but also specify the retry argument, because a number of the parameters are still unidentifiable with my ballpark starting values. So the question is does the initial argument overwrite the values that would have been obtained by specifying the retry argument? I want to make sure that the same initial values aren't be used for the 1st, 2nd, . . . iteration of the mark function calls.

Code: Select all

mark(data.proc, data.ddl, initial=init, retry=2, . .

Thanks.

If retry is set, it uses final values from previous run except that it sets all singular betas to 0. --jeff

That's what I assumed, but just wanted to double check.

Thanks.
