Modely s náhodnými efekty v analýze přežívání

The aim of this paper is to present an overview of the methods used in modeling survival data. Since the topic of my future Ph.D. thesis is Statistical models for correlated survival data we introduce the use of frailties as an equivalent of random effects in common statistical modeling together with its connection to correlation. Frailty model, how model with frailties is called, uses frailties as a parameter for individuals. Those who are most frail will experience an event earlier than others
