Robust-design Multi-Strata Model

The multi-strata model of Brownie et al. (1993) and Hestbeck et al. (1991) allows animals to move between strata with transition probabilities, and has been extended to incorporate the robust design. Two versions are available. The open robust-design multi-strata model allows animals to immigrate and emigrate from the study area during a primary capture occasion. The closed robust-design multi-strata model assumes that the population is closed during a primary session.

The robust-design multi-strata model uses LLL... encounter histories, because information on dead recoveries is not used. The robust-design multistrata model with live and dead recoveries uses the information from dead encounters, so requires the LDLDLD... encounter history format.
