Package: ipsecr Type: Package Title: Spatially Explicit Capture-Recapture by Inverse Prediction Version: 1.4.4 Date: 2025-06-10 Description: Estimates the density of a spatially distributed animal population sampled with an array of passive detectors, such as traps. Models incorporating distance-dependent detection are fitted by simulation and inverse prediction as proposed by Efford (2004) .
