Actuaries have access to a wealth of individual data in pension and insurance portfolios, but rarely use its full potential. This book will pave the way, from methods using aggregate counts to modern developments in survival analysis. Based on the fundamental concept of the hazard rate, Part I shows how and why to build statistical models, based on data at the level of the individual persons in a pension scheme or life insurance portfolio. Extensive use is made of the R statistics package. Smooth models, including regression and spline models in one and two dimensions, are covered in depth in Part II. Finally, Part III uses multiple-state models to extend survival models beyond the simple life/death setting, and includes a brief introduction to the modern counting process approach. Practising actuaries will find this book indispensable, and students will find it helpful when preparing for their professional examinations.

The Rapid Assessment Program (RAP) surveys have been a highly effective conservation tool for Conservation International and a multitude of partners. This exciting book outlines the inception, history, and achievements of this program during its first two decades, 1990-2010. The editors profile nearly eighty expeditions to some of the most remote but highly threatened sites around the world and relay personal stories from the field. Illustrated with hundreds of photos taken during the RAP surveys, this book includes the first images of many newly discovered species of animals and plants and other rarely photographed jewels of terrestrial, freshwater, and marine biodiversity.
