| Abstract: | 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. |
| Keywords: | Heterogeneous detection models Orthogonal parameter estimators Profile log likelihoods Timed species counts Zero inflation Zero-modified distributions |
