Across the insurer, there are many areas for potential applications of statistics. Additional applications have become possible because of the technological development of computer systems and data base tools. Give an example of a more recent “business intelligence” application of statistical analysis for insurer operations. Be sure to describe the neccsary data, the methodology, and the types of decisions that can be informed by the results of the analysis.
