I want to determine if there is a correlation between weed plant species density and habitation (buildings).
Both data sets are points. The weed species has an 'abundance value' (i.e., one point may represent any value captured in an attribute field). The habitation point data set is one 'building' per point.
I want to test both; for 1) all species relationship to buildings, and 2) per single species to buildings (i have 115 species). The relationship should be tested up to about 3000 m from each species point. Locations are not coincident.
I only have ArcGIS 10.4 with Spatial Analyst, Geostatistical Analyst, and other common extensions. I would also be able to use QGis.
I have little knowledge of R, python, etc.
My hypothesis would be that 'weed species are more abundant close to habitation and more so the denser habitation is'.
