Spatial Graph-Theoretic Genetic Gravity Modelling

Implementation of spatial graph-theoretic genetic gravity models. The model framework is applicable for other types of spatial flow questions. Includes functions for constructing spatial graphs, sampling and summarizing associated raster variables and building unconstrained and singly constrained gravity models.



  • First release of package for Spatial Graph-theoretic Genetic Gravity Modelling


  • Added log likelihood to the gravity function, which is the current preference over AIC in evaluating competing models
