WebMar 31, 2024 · This test is extended to dynamic occupancy models of MacKenzie et al. (2003) by using the occupancy estimates for each season obtained from the model. These estimates are then used to compute the predicted and observed frequencies separately within each season. Webdynamic occupancy model (MacKenzie et al. 2003 ), alternatively called the multi- season occupancy model, has become a widely used model to learn about the colonization and extinction processes. Occupancy mod-els rely on a hierarchical framework (either implicit or explicit) to account for species that may be present at a site but go undetected. hiscox fleet insurance
