Description

<p>Effects of the number of crime locations on geographic profiling models were investigated. The data of 55 serial residential burglaries comprised of up to 15 burglaries committed by each burglar were sampled. The accuracy of 3 geographic profiling models: center of the circle, spatial mean, and CMD models were compared in each of 3 to 15 crime locations. The error distance was used for measuring the accuracy of the models. Multiple comparisons showed that CMD method had shorter error distances than center of the circle method when seven, or more crime locations were used. These results suggested that the number of crime locations differentially affected the accuracy of each model.</p>
