PRESENCE 12.7 - Estimates patch occupancy rates and related parameters. This work is in collaboration with Darryl MacKenzie, and is largely funded by the Amphibian Research and Monitoring Initiative (ARMI). Contact Darryl if you would like to learn more about this project.
RPresence - Provides an R interface for running occupancy models available in Program PRESENCE plus some additional helpful routines.
GENPRES - Generates patch occupancy data and analyzes using program PRESENCE.
OccPower.xlsx - Spreadsheet to compute power to detect difference in 2 independent occupancy estimates using asymptotic approximations described in Guillera-Arroita et. al. (2012).
