SpatialPack: Tools for assessment the association between two spatial processes

This is the homepage for the R package SpatialPack developed in the Department of Mathematics at Universidad Técnica Federico Santa María, Chile by Felipe Osorio and Ronny Vallejos, with contributions of Francisco Cuevas, Diego Mancilla and Jonathan Acosta.

It provides tools to assess the association between two spatial processes. Currently, four 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. SpatialPack gives methods to complement methodologies that are available in geoR for one spatial process.

  1. Tjostheim's Coefficient.
  2. A Modified Correlation Coefficient Test.
  3. The Codispersion Coefficient.
  4. Modified F Test for assessing multiple correlation.
