detect (version 0.3-2)

detect-package: Analyzing Wildlife Data with Detection Error

Description

The package implements models to analyze site occupancy and count data models with detection error. The package development was supported by the Alberta Biodiversity Monitoring Institute (ABMI) (http://www.abmi.ca/) and the Boreal Avian Modelling (BAM) Project (http://www.borealbirds.ca/).

Details

svocc: single visit occupancy model (Lele et al. 2011, Moreno et al. 2010). svabu: single visit abundance model based on conditional maximum likelihood (Solymos et al. 2012). cmulti: conditional multinomial maximum likelihood estimation for removal and (point count) distance sampling, efficient and flexible setup for varying methodologies (Solymos et al. 2013).
