On 14 November 2013, Emiel Caron has successfully defended his PhD thesis at Erasmus University Rotterdam with the title “Explanation of Expceptional Values in Multi-dimensional Business Databases”. Emiel has studied the question of extending the functionality of multi-dimensional business databases with diagnostic capabilities to support managerial decision-making. He developed formal methods for identifying exceptional values in OLAP approaches and offering automated explanations for these values. The methods Emiel developed will increase the efficiency of business analytics in this age of big data. Congratulations Emiel!
