This chapter relaxed the parametrically restrictive parameterization for time considered in Chapter 8, adopting instead a nonparametric set of models in which the exact form for the effect of time was left as an arbitrary function. This proportional hazards (or Cox) model provides a very rich framework for data analysis, enabling not only the consideration of factors that were measured at the beginning of follow-up but also to update the risk status over time. Exercises are provided at the end of the chapter.

Keywords: regression; piecewise constant hazards modle; proportional hazards model; cox model
