Arvustused

This book is very useful for researchers and students in different scientific areas social sciences and humanities, medicine, in



general every science where studies measuring time changes in variables are



conducted...As the author explains, this book is written from the



perspective of an absolute beginner comprehensible and with a lot of examples



in the text, tables and graphs. It goes beyond an introductory textbook on this



topic, because it presents not only non-parametric models, semi-parametric



models, parametric models, model-building and model diagnostics, but it is focused also on some more recent techniques like frailty and recurrent event



history models, discrete-time models, multistate models, competing risk



analysis and sequence analysis...Everyone who would like to start with Survival and



Event History analysis or to get more knowledge of Survival and Event History



analysis could do this by reading this book Stanislava Yordanova Stoyanova Methodspace
