Applied survival analysis: regression modeling of time to event data

This book fills this gap, providing a comprehensive, self-contained introduction to regression modeling used in the analysis of time-to-event data in epidemiological, biostatistical, and other health-related research. Unlike other texts on the subject, it focuses almost exclusively on practical applications rather than mathematical theory and it offers clear, accessible presentations ofmodern modeling techniques supplemented with real-world examples and case studies.
