Spatially Explicit Capture-Recapture by Inverse Prediction

This package implements a simulation-based 'inverse prediction' algorithm for fitting spatially explicit capture-recapture models to data from tricky detectors such as single-catch traps (Efford, 2004; Efford, Dawson and Robbins, 2004; Efford, 2023).

ipsecr depends on secr 4.5.8 or later. It improves on the functionality of ip.secr in earlier versions of secr. Many functions mirror those in secr.

ipsecr 1.4.0 is available on CRAN.

The code here is under development. It may be installed using

devtools::install_github("MurrayEfford/ipsecr")

Compilation of C++ code is required.
