Codispersion Map for Rectangular Grids
The codispersion coefficient quantifies the association between two spatial processes for a particular direction (spatial lag) on the two-dimensional space. The R function hcodisp.map provides a graphical tool called codispersion map to visualize the spatial correlation between two sequences measured for regular lattices on the plane.
