In medical studies one is often interested in studying the expected time until the death of a patient, undergoing a specific treatment. Similarly, in technological tests, one is often interested in studying the amount of time until a device subjected to specified conditions fails. Times until death and times until failure are examples of survival data. The statistical analysis of survival data is based on the use of specific data models and probability distributions. In this chapter, we present several relevant topics of survival analysis and their application to survival data using STATISTICA and SPSS.
