Predictive modeling to gain insights in political preference in a multi-party system Stiene Praeta, Peter Van Aelstb and David Martensa aDepartment of Engineering Management, University of Antwerp bDepartment of Political Science, University of Antwerp December 18, 2018 Abstract In political sciences there is a long tradition of trying to understand party prefer- ences and voting behavior to explain political decisions.
