Abstract

This book provides a comprehensive and rigorous exploration of modern survival analysis with a focus on frailty models for unobserved heterogeneity. The book introduces the mathematical foundations of survival analysis, regression models, Laplace transforms, and classical frailty distributions before presenting two innovative frailty models: the Quasi-Xgamma and the Mixed Gamma-Exponential models. It details their theoretical development, parameter estimation, goodness-of-fit procedures, and practical applications in medical, actuarial, and reliability research. Combining solid statistical theory with methodological innovation, this book is a valuable resource for researchers, graduate students, and professionals seeking advanced approaches to modeling time-to-event data and validating flexible survival models.
