xnicher: Estimates Ecological Niche Models Using Ellipses
Ecological niche model estimation using ellipsoidal geometry
under an M hypothesis. Fits nine likelihood families
(presence-only, weighted, inverse-probability-weighted, skew-normal,
skew-normal-weighted, skew-t, skew-t-weighted, ncst, and
ncst-weighted) via multi-start optimisation with Sobol sequences.
Methods for the optimisation of ellipses parameters are as described
in Jimenez et al. (2022) <doi:10.1016/j.ecolmodel.2021.109823>.
