Package: ECDFniche 1.0

ECDFniche: Empirical Cumulative Distribution Function Niche Modeling Tools

Simulate ecological niche models using Mahalanobis distance, transform distances to suitability using the empirical cumulative distribution function (ECDF) and the chi-squared. Provides a way to reproduce the use of ECDF in other modeling environments as proposed in Esser et al. (2026) <doi:10.1016/j.ecolmodel.2026.111795>.
