It seems clear that both age and gender have an e ect on someone’s survival, how do we come up with a model that will let us explore this relationship? Even if we set Died to 0 and Survived to 1, this isn’t something we can transform our way out of - we need something more. One way to think about the problem - we can treat Survived and Died as

Lecture 15 Introduction to Survival Analysis

– The survival function gives the probability that a subject will survive past time t. – As t ranges from 0 to ∞, the survival function has the following properties ∗ It is non-increasing ∗ At time t = 0, S(t) = 1. In other words, the probability of surviving past time 0 is 1. ∗ At time t = ∞, S(t) = S(∞) = 0. As time goes to
