Statistical Models for Aggregate Crime Data workshop
This is a two-day hands-on training workshop led by Dr Les Humphreys and Professor Brian Francis, Lancaster University, and Rebecca Pillinger, University of Edinburgh.
Course Content:
This course will explore methods for analysing aggregate crime data with a particular focus on analyzing change over time using recorded crime data and survey data to illustrate the value of these approaches in understanding changes in crime in Scotland, and domestic violence in England and Wales. This type of data is not normally distributed; it is count data and is therefore Poisson distributed as it takes discrete non-negative values. Hence it is not appropriate to fit linear models to this type of outcome. Generalised Linear Models (GLMs) provide a method to estimate regression models where the outcome variable is not normally distributed (but where the distribution belongs to the family of exponential distributions).
This course is aimed at students and researchers who are engaging in research that explores change over time in social processes and will explore the basic principles of Poisson log-linear models and rate models. In addition, the course will cover the basics of changepoint models and spline models. Changepoint models allow us to detect whether and when changes in crime trends have taken place, and spline models allow us to estimate smooth regression curves.
Course objectives:
• To teach participants the principles underlying change point models and spline models and how these approaches differ from other methods of analysing repeated data
• To illustrate the application of these approaches using specific examples of crime in Scotland and domestic violence in England and Wales
• To give participant’s practical hands on experience of fitting GLM’s, changepoint models and spline models
Learning outcomes:
By the end of the workshop participants will:
• Understand the theory and methods behind GLMs, changepoint models, and spline models
• Be able to apply these techniques to suitable data making relevant assumptions
• Be confident in accurately interpreting the results of this type of analysis
• Date: Wednesday, May 13, 2015 - 09:30 to Thursday, May 14, 2015 - 17:00
