Bayesian belief networks (BBN) and GIS can be used as decision aides to give an idea of probability of events unfolding.

GIS and Stratified Heterogeneity

A method to measure uneven distribution of landscape or population features in a given space is stratified heterogeneity.

Using R with GIS Software

Mark Altaweel

With the utility of R, many popular statistical procedures and more advanced analyses, including a variety of simulation applications, can be applied directly within GIS tools such as QGIS.

From Davies et al., 2016: "the results show good qualitative agreement, with 26 of the 33 boroughs showing rioter percentages in the same or adjacent bands as the data. The remaining discrepancy may be accounted for by factors specific to the London disorder, such as communication between groups, other activity patterns occurring at the time, or social factors beyond the scope of this work.
