Description:
External data can often be useful in improving estimation of operational risk loss distributions. This paper develops a systematic approach that incorporates external information into internal loss distribution modelling. The standard statistical model resembles bayesian methodology or credibility theory in the sense that prior knowledge (external data) has more weight when internal data is sparse than when internal data is abundant
