Correlation is mutual relationship between numerical variables. Spatial correlation differs from non-spatial by including location parameters (usually coordinates). Usually, the dependence of correlation from distance is studied or the weight of observation pairs is set dependent on their distance. Regression is dependence of a numerical variable on explanatory numerical variables.
Both correlation and regression can be calculated locally at each location or grid node. The strength and significance and other parameters of relationshiops can be presented as cartograms.
