An update version of the CrimeStat spatial statistics program has just
been released by the National Institute of Justice's (NIJ) Crime Mapping
Research Center. CrimeStat is a free program for the statistical analysis
of crime and other incident locations, developed by Ned Levine & Associates
of Annandale, VA. The program is Windows based and interfaces with most
desktop GIS programs, including MapInfo. The program reads 'dbf' files and
outputs results in MapInfo's 'mif' format.
The aim is to provide supplemental statistical tools to aid analysts and
researchers in statistically describing the distribution of crime incidents
or other types of events (e.g., describing clusters of crime incidents;
describing shifts in the spatial distribution of shopping trips; describing
the distribution of pedestrian accidents relative to the underlying
population distribution).
Version 1.1 is an update to the first version which was released
in November 1999 and fixes some problems associated with 1.0 (e.g.,
improved performance in Windows 98), adds new database features, (e.g., the
ability to handle missing values), makes improvements to some of the
existing routines (e.g., edge corrections to Ripley's K statistic), and
adds new journey to crime calibration and estimation routines. The latter
technique is an adaptation of location/travel behavior theory. It could be
used, for example, to identify an optimal location to place a senior
citizen center given the distribution of seniors in a community and
assumptions about their travel behavior.
The program is fully documented with update notes and a new
chapter on journey to crime estimation. There are also sample data sets
provided. The new version can be downloaded from either NIJ's Crime
Mapping Research Center web site:
