SELT Survey Results

This course introduces survival models and discusses their rationale, their estimation and their application to mortality. Topics covered will include: an introduction to the life table; survival models; estimation procedures for lifetime distributions; statistical models of transfers between multiple states; maximum likelihood estimation of transition intensities for such models; binomial model of mortality including estimation and comparison with multiple state models; exposed to risk and methods for smoothing crude mortality rate data.     

Learning Outcomes

Upon successful completion, students will have the knowledge and skills to:

  1. Explain the concept of survival models;
  2. Describe the estimation procedures for lifetime distributions;
  3. Understand and describe statistical models of transfer between multiple states, including processes with single or multiple decrements, and derive relationships between probabilities of transfer and transition intensities;
  4. Derive maximum likelihood estimators for the transition intensities in models of transfers between states with piecewise constant transition intensities;
  5. Describe how to estimate transition intensities depending on age, exactly or using the census approximation; and,
  6. Communicate how to test crude estimates for consistency with a standard table or a set of graduated estimates, and describe the process of graduation.

Research-Led Teaching

This course involves an intermediate level of programming with R, including model fitting, graphical analysis and forecasting. In the lectures and computer labs (from week 2 to week 8), we will use real-life datasets to demonstrate the applications of Survival Models in R. Apart from that, additional research articles including journal publications will be provided. Those articles are good examples of how to use appropriate techniques of Survival Models to analyse and solve research questions step-by-step.

Examination Material or equipment

The mid-semester and final exam will be administered online and be open book. Examination materials and conditions will be noticed to all students via Wattle and the examination office.

Required Resources

Lecture notes and other course materials will be updated weekly with the progress of this course on Wattle.

Staff Feedback

Students will be given feedback in the following forms in this course:

  • Tutorial solutions and discussions (online and local tutorials)
  • lecturer consultations (online)

Student Feedback

ANU is committed to the demonstration of educational excellence and regularly seeks feedback from students. Students are encouraged to offer feedback directly to their Course Convener or through their College and Course representatives (if applicable). The feedback given in these surveys is anonymous and provides the Colleges, University Education Committee and Academic Board with opportunities to recognise excellent teaching, and opportunities for improvement. The Surveys and Evaluation website provides more information on student surveys at ANU and reports on the feedback provided on ANU courses.

Other Information


Your final mark for the course will be based on the raw marks allocated for each assignment or examination. However, your final mark may not be the same number as produced by that formula, as marks may be scaled. Any scaling applied will preserve the rank order of raw marks (i.e. if your raw mark exceeds that of another student, then your scaled mark will exceed or equal the scaled mark of that student), and may be either up or down.

Support for Students

The University offers a number of support services for students. Information on these is available online from http://students.anu.edu.au/studentlife/

Technology, Software and Equipment

This course involves intermediate level of programming with R, which is a powerful and free statistical package widely used by industrial professionals and academics.

Co- Teaching

STAT3032/STAT4072/STAT7042/STAT8003 will be taught jointly. There may be some material which is only relevant to some of these codes. This will be clearly identified during the lecture and/or tutorial. The different cohorts of students will also be treated separately in grading and any scaling that is applied.

ANU has educational policies, procedures and guidelines, which are designed to ensure that staff and students are aware of the University’s academic standards, and implement them. Students are expected to have read the Academic Misconduct Rule before the commencement of their course. Other key policies and guidelines include:

Assessment Requirements

The ANU is using Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. For additional information regarding Turnitin please visit the Academic Integrity . In rare cases where online submission using Turnitin software is not technically possible; or where not using Turnitin software has been justified by the Course Convener and approved by the Associate Dean (Education) on the basis of the teaching model being employed; students shall submit assessment online via ‘Wattle’ outside of Turnitin, or failing that in hard copy, or through a combination of submission methods as approved by the Associate Dean (Education). The submission method is detailed below.

Moderation of Assessment

Marks that are allocated during Semester are to be considered provisional until formalised by the College examiners meeting at the end of each Semester. If appropriate, some moderation of marks might be applied prior to final results being released.


Course content delivery will take the form of weekly on-campus lectures (recorded and available via echo360 on Wattle),  weekly online (Zoom) consultation, and weekly tutorials, delivered in hybrid format (on campus, live through scheduled Zoom sessions and as pre-recorded videos). Information regarding tutorial enrolments for these options will be provided on Wattle during O-week prior to the start of the semester.


Any student identified, either during the current semester or in retrospect, as having used ghost writing services will be investigated under the University’s Academic Misconduct Rule. Centrally scheduled examinations through Examinations, Graduations & Prizes will be timetabled prior to the examination period. Please check ANU Timetabling for further information.
