I have been looking around online and whenever I see reference to OLS or GWR, few to no one using point (x,y) data in their tutorials. Why is this and is there a way to do a "what is the relationship between these variables" analysis without attaching the x,y point data to polygons. I am comfortable making grids or associating individual points with polygons, but I would rather not lose any granularity if there's another option to be able to work with the point data without aggregating. Thanks.
