Optimal Bandwidth Selection
Figure 6 shows the log likelihood surfaces computed using the planar and network KDE methods. To recap, these represent the most likely bandwidths that would lead to the distribution of crime events observed examined during the (60-day) calibration window. In both cases, a well-defined maximum is evident; while this is less visually striking in the case of the network KDE, the optimum is readily discernible when the data are rescaled to show only the highest likelihood values. The optimal bandwidths are 55 days and 610 m
