Spatial Misalignment Between Two Point Processes with an Application to Police Use of Force and Violent Crime (309932)

Keywords: use of force, point process, spatial misalignment

In order to study the relationship between violent crime and police use of force, existing work has relied on the spatial aggregation of violent crime due to model limitations. However, when we aggregate point-level data, such as violent crime, we lose valuable information about the distribution of the points over space as well as event-level information, such as the category of crime for a given event. There is some existing work in the areal data literature of combining multi-type outcomes through shared component models. In the point process literature, comparing point processes has often been done through case-control studies. We investigate several new methods, including approaches that build upon shared component models and case-control methods, to retain the point-level nature of violent crime to analyze the relationship between violent crime and police use of force.
