PT Journal AU Marcon, E Traissac, S Puech, F Lang, G TI Tools to characterize point patterns: dbmss for R SO Journal of Statistical Software JI Journal of Statistical Software PY 2015 BP 1 EP 15 VL 67 IS Codesnippet3 DE Point patterns; R; Spatial structure AB The dbmss package for R provides an easy-to-use toolbox to characterize the spatial structure of point patterns. Our contribution presents the state of the art of distance-based methods employed in economic geography and which are also used in ecology. Topographic functions such as Ripley’s K, absolute functions such as Duranton and Overman’s Kd and relative functions such as Marcon and Puech’s M are implemented. Their confidence envelopes (including global ones) and tests against counterfactuals are included in the package. © 2015, American Statistical Association. All rights reserved. ER
