Spatial factor analysis : a new tool for estimating joint species distributions and correlations in species range [Methods in Ecology and Evolution]

par Frédéric Magné - publié le , mis à jour le

Predicting and explaining the distribution and density of species is one of the oldest concerns in ecology. Species distributions can be estimated using geostatistical methods, which estimate a latent spatial variable explaining observed variation in densities, but geostatistical methods may be imprecise for species with low densities or few observations. Additionally, simple geostatistical methods fail to account for correlations in distribution among species and generally estimate such cross-correlations as a post hoc exercise.(...)
