This course provides students with the mathematical background to non-life models, such as medical and automobile insurance. Topics covered include severity loss models for claims and frequency models for occurrence of those claims. The severity and frequency models are then brought together, and aggregate models are addressee. During the semester, students are presented with modification to both severity and frequency models including deductibles and claims limits. The course emphasizes applications of statistical principles in actuarial models and modeling. The material covered in this course may help students prepare for SoA Exam STAM and CAS Exam MS II.
