This is a rather technical dive into the near repeat pattern analysis and load forecasting features that we've built into HunchLab. Both of these features are aimed at helping a law enforcement agency to better predict risk levels across their jurisdictions and allocate resources according. While no application of predictive analytics will be perfect, forecasting risk based on models of the past can help officers and analysts to anticipate the appropriate next steps.
Near repeat pattern analysis helps officers quantify the risk that arises from multiple incidents happening close to one another in space and time. What we are quantifying is how the fact that your neighbor's house is burgled raises your risk of a burglary in the coming days and weeks.
With load forecasting we are looking at cyclical temporal patterns in incidents. How does the time of year, time of day, and day of week change the levels of crime incidents that we should expect across a jurisdiction? By modeling these cyclical patterns we can project crime levels into the future, helping law enforcement agencies to allocate resources appropriately as well as better manage organizational accountability.
