Description:
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>.
