datasets

Tools to assess the association between two spatial processes. Currently,
several methodologies are implemented: A modified t-test to perform hypothesis testing
about the independence between the processes, a suitable nonparametric correlation
coefficient, the codispersion coefficient, and an F test for assessing the multiple
correlation between one spatial process and several others. Functions for image
processing and computing the spatial association between images are also provided.
Functions contained in the package are intended to accompany Vallejos, R., Osorio, F.,
Bevilacqua, M. (2020). Spatial Relationships Between Two Georeferenced Variables:
With Applications in R. Springer, Cham <doi:10.1007/978-3-030-56681-4>.
