Preface

In recent years, a large variety of textbooks dealing with time-to-event analysis has been published. Most of these books focus on the statistical analysis of observations in continuous time. In practice, however, one often observes discrete event times— either because of grouping effects or because event times are intrinsically measured on a discrete scale. Statistical methodology for discrete event times has been mainly presented in journal articles and a few book chapters. In this book we introduce basic concepts and give several extensions that allow to model discrete time data adequately. In particular, modeling discrete time-to-event data strongly profits from the smoothing and regularization methods that have been developed in recent decades. The presented approaches include methods that allow to find much more flexible models than in the early times of survival modeling. The book is aimed at applied statisticians, students of statistics and researchers from areas li
