Introduction

In this chapter, I discuss several topics that are common to many different methods of survival analysis:

  • censoring, a nearly universal feature of survival data.

  • common ways of representing the probability distribution of event times, especially the survivor function and the hazard function.

  • choice of origin in the measurement of time, a tricky but important issue that is rarely discussed in the literature on survival analysis.

  • basic data structure required for most computer programs that perform survival analysis.
