cascad: A new certifying organization to help double-check scientific results

While scientific findings need to be assessed by peers and journal referees, the confidentiality of original data often makes the process arduous. An accredited organization launched by Christophe Pérignon (HEC Paris) and colleagues with access to the original research data can now ensure reproducibility of results. This not only promises huge gains in time and effort for researchers but will also shore up trust in scientific results.

Analytics in the Era of Big Data: Opportunities and Challenges

Data Analytics

This special issue of Knowledge@HEC highlights several research projects and teaching initiatives at HEC Paris in the context of big data and business analytics. Nowadays it does not take much to convince students or managers alike of the importance of data for businesses. As Wedel and Kannan (2016) put it, “data is the oil of the digital economy”. Indeed, data is completely transforming organizations, and data-driven decision making is becoming more and more a part of a company’s core. In an increasing digital world, all of us are walking data generators, leaving long data trails: we have more data on everything.
