Crimestat 3 (opens new webpage)
CrimeStat 3 is a spatial statistics program for the analysis of crime incident locations, developed by Ned Levine & Associates under the direction of Ned Levine, PhD, that was funded by grants from the National Institute of Justice. The program is Windows-based and interfaces with most desktop GIS programs. The purpose is to provide supplemental statistical tools to aid law enforcement agencies and criminal justice researchers in their crime mapping efforts. CrimeStat is being used by many police departments around the country as well as by criminal justice and other researchers.
The tool enables a variety of techniques including, hotspot analysis; journey to crime and regression modeling. A full software manual is available on the same website.
Crime Dispersion Index
This program will calculate Offense Dispersion Index and associated values for specific crime data in a fixed format. Using dispersion analysis, a technique that measures the relative dispersion of a crime increase across a region allows for the identification of particular spatial units that are sufficiently influential to drive up the overall jurisdictional crime rate.
A combination of the order of areal units from a dispersion analysis with a measure of the local level of spatial association is used to develop a tool that can identify clustered areas of emerging crime problems. The identification of these second-order spatial processes may be beneficial to police departments and crime prevention practitioners who are interested in the identification of statistically significant clusters of emerging crime hotspots.
