Principles of the CoBRA Method
The Cost Estimation, Benchmarking, and Risk Assessment (CoBRA) method combines multiple prediction approaches in that it aggregates techniques representing expert-based and data-driven estimation paradigms, within one hybrid estimation method. This chapter introduces the basic idea and terminology of the CoBRA method. Moreover, this chapter specifies the basic roles considered in the CoBRA method and the essential conceptual elements of the method.
