Daniele Da Re is a Postdoctoral Researcher, at the University of Trento, Italy. Cedric Marsboom is CTO of Avia-GIS, Belgium. During the 2023 MOOD Summer School, these two experts hosted a session to give an introduction to correlative SDMs in R using virtual species as example. A tutorial was provided and both the GLM and RF methods were explained. We first analyze each algorithm separately and the produced ensemble models. In the final part of the lesson we focused on discussing different predictive accuracy metrics.
