geostatistics where each point is associated with a value (air pollution

matters in point pattern analysis. Do maple trees tend to be located near
other maple trees? Are there areas with unusually high or low concentrations
of breast cancer?

key point pattern methods including Ripley’s K and Ghat and Fhat
plots to test for “complete spatial randomness.”
