During the last two decades actuarial research has developed in a more applied direction. Although the original risk models generally served as convenient and sometimes tractable mathematical examples of general probabilistic and/or statistical theories, nowadays models and techniques are encountered that can be considered to be typically actuarial. Examples include ordering of risks by dangerousness, credibility theory and techniques based on IBNR models. Not only does this book present the underlying mathematics of these subjects, but it also deals with the practical application of the techniques. In order to provide results based on real insurance portfolios, use is made of three software packages, namely SLIC performing stop-loss insurance calculations for individual and collective risk models, CRAC dealing with actuarial applications of credibility theory, and LORE giving IBNR-based estimates for loss reserves. Worked-out examples illustrate the theoretical results. This book is intended for use in preparing university actuarial exams, and contains many exercises with varying levels of complexity.

APL, an eminently suitable programming language for actuaries, is shown in this book to be powerful in dealing with life and non-life actuarial problems. It is not only useful in its performance of mathematical calculations, but also for the administrative tasks connected with some insurance problems. This introduction to APL puts special emphasis on practical insurance applications. The main features of the APL language are described as well as the special APL symbols essential for actuarial applications. Topics such as IBNR, credibility and forecasting are examined. Software available for solving practical insurance problems is discussed, and exercises and solutions are available on a diskette. This diskette can be ordered, free of charge, by completing the coupon to be found in the book.
