Morgan, B.J.T., Revell, D.J. & Freeman, S.N. 2007 A note on simplifying likelihoods for site occupancy models. Biometrics 63: 618-621

Abstract

Summary: We show how a simple reparameterization can reduce the number of parameters that need to be estimated by numerical maximum likelihood in site occupancy models. Three examples are provided.

Key Words: Heterogeneous detection models; orthogonal parameter estimators; profile log likelihoods; times species counts; zero inflation; zero-modified distributions.
