Loss Models

A modern practical guide to building and using actuarial models.

Loss Models: From Data to Decisions is organized around the principle that actuaries build models in order to analyze risks and make decisions about managing the risks based on conclusions drawn from the analysis. In practice, one begins with data and ends with a business decision. The book flows logically from this principle. It begins with a framework for model building and a description of frequency and severity loss data typically available to actuaries. Parametric models are emphasized throughout.

The frequency and severity models are used in building aggregate loss models, in credibility-based pricing models, and in loss analysis over multiple time periods.

Designed as both an educational text as well as a professional reference, Loss Models:

Assumes little prior knowledge of insurance systems

Features many fascinating examples taken from insurance files

Contains a major instructive case study continued through each chapter

Covers the classical areas of risk theory and loss distributions

Gives a practical but rigorous treatment of modern credibility theory

Uses standard statistical concepts, methods, and notation

Provides modern computational algorithms for implementing methods

Includes free companion software available from an FTP site

Deals with many topics on CAS 4B and SOA 151 and 152 actuarial exams

Includes many exercises based on past CAS and SOA exams.
