HunchLab: Transforming Crime Data Visualization

HunchLab offers a new approach to analyzing crime density changes, receiving notifications, and accessing detailed information. Unlike traditional methods, it is not designed for comprehensive understanding. With 1.5 million incidents annually across 40 crime classifications, HunchLab assists law enforcement agencies in solving the "Data Tornado" dilemma. By leveraging statistical analysis, it provides insightful visualizations for better decision-making. Utilize HunchLab to track shifting crime densities and enhance proactive policing strategies.

  8. How Do We Figure out Density Change? • Take an area or *many* areas to evaluate • Use statistics to compare historical norms to current densities • But… how? • Call crimes balls in a bag.

  9. That’s Right, Balls In a Bag That’s Right, Balls in a Bag A bag has 20 black balls and 80 white balls. Choose 5 at random. What is the chance of getting 3 black balls? Vary number of balls chosen and you get a Hypergeometric Distribution

  10. Crimes -> Balls -> Probabilities Crimes è Balls è Probabilities

  11. Lather, Rinse, Repeat Lather, Rinse, Repeat
