Learning Outcomes

Learning Outcomes

Having successfully completed this module you will be able to:

  • the key features of lifetime data, including censoring, and of probability models for lifetime data: survival function, hazard and force of mortality
  • the theory underlying survival models and their estimation and of how to use R to fit models, including the Kaplan-Meier estimate of the survival function, parametric models and the Cox regression model
  • models for human mortality, including how to compute and interpret the life table in a variety of contexts
  • binomial and Poisson models of mortality and models of mortality and similar events which are specified as continuous-time discrete-state Markov processes
  • the need to graduate crude data on mortality rates and an understanding of how to compare crude mortality rates against a standard of graduated set of rates
  • analyse and interpret data, and especially to adopt a critical approach to numerical data
  • solve problems, and especially to apply ideas learnt in one context to other contexts

Syllabus

• Introduction to concepts of modelling, survival data and survival models; censoring; survival and hazard functions. • Estimating the survivor function non-parametrically (Kaplan-Meier and Nelson-Aalen estimators); parametric survival models; estimation using maximum likelihood. • Regression models for survival data; proportional hazards; the Cox regression model; accelerated failure time models. • Introduction to continuous-time, discrete-state Markov models; two-state and multiple-state models; Kolmogorov equations; estimating the parameters of multiple-state models. • Models for human mortality; the life table: theory and applications. • Comparison of models of mortality: Binomial, Poisson and multiple-state models. Estimation and inference using maximum likelihood and other methods. • Exposure to risk; the principle of correspondence; estimating the exposed-to-risk with aggregate data. • Comparison of mortality experiences; mortality rates and standardised mortality ratios; statistical tests appropriate for the comparison. • Graduation of mortality data; reasons for graduation; methods of graduation; tests of adherence to data and smoothness of a graduation. • Using R to analyse lifetime and survival data
