ABSTRACT
This chapter discusses two data sets. The first data shows from a research programme investigating motion sickness at sea. Second data set shows from 50 female black ducks from two locations in New Jersey that were captured and fitted with radios. Both these data sets involve time to the occurrence of a particular event. Such data are generally referred to by the generic term survival data even when the end point or event being considered is not death. Of central importance in the analysis of survival data are two functions describing the distribution of survival times, the survival function and the hazard function. In the analysis of survival data, it is often of interest to assess which periods have high or low chances of the event of interest occurring amongst those alive at the time.
