Abstract:
Recent advances in police open data initiatives across the United States allow for analyses of datasets in criminology and policing across a variety of spatial scales. However, existing statistical methods often do not allow for the utilization of the original spatial granularity or event-level information present in these complex datasets.
My dissertation addresses gaps in spatial statistical methodology for analyzing crime and policing data. In particular I (1) propose a new approach to analyze areal crime data through the use of both spatial and social dependence between communities, (2) develop a two-stage approach to study marked point process data with flexible relationships between the location-determination and the mark-determination stages of the point process model, (3) adapt a new shared component model for point process data that allows for flexible characterization of shared spatial patterns between point patterns, and unique drivers of each point process, and (4) explore a method for privatizing data that preserves its statistical utility.
