STATS 731 : Bayesian Inference

Science

2024 Semester Two (1245) (15 POINTS)

Course Prescription

A course in practical Bayesian statistical inference covering: the Bayesian approach specification of prior distributions, decision-theoretic foundations, the likelihood principle, asymptotic approximations, simulation methods, Markov Chain Monte Carlo methods, the BUGS and CODA software, model assessment, hierarchical models, application in data analysis.

Course Overview

Over the last decade, the Bayesian approach has revolutionised many areas of applied statistics such as Biometrics, Econometrics, Market Research, Statistical Ecology, and Physics. Its rise and enormous popularity today are due to the advances made in Bayesian computation through computer-intensive simulation methods. Knowledge of Bayesian procedures and software packages will become indispensable for any career in Statistics. We will be using the software packages R and JAGS (or WinBUGS/OpenBUGS) for Bayesian computation, as well as some R packages. Statistics students from both theoretical and applied ends of the subject may find this course useful in a range of areas in research and industry since Bayesian inference provides (i) a unified and compelling framework for reasoning in the presence of uncertainty; and (ii) the foundation of many popular machine-learning methods used in industry.

This course will introduce the theory of Bayesian inference, computer-intensive simulation techniques for posterior computation, and put strong emphasis on modern, applied Bayesian data analysis.

Workload Expectations

This course is a standard 15-point course and students are expected to spend 150 hours in total over the semester for this course.

For this course, a typical weekly workload includes:

  • 2 hours of lectures
  • A 1-hour tutorial
  • 2 hours of reviewing the course content
  • 5-7 hours of work on assignments and/or test preparation

Delivery Mode

Campus Experience

Attendance is expected at scheduled activities including lectures and tutorials, to complete components of the course. Lectures will be available as recordings. Tutorials will not be recorded but worked solutions will be available. Attendance on campus is required for the test and exam. The activities for the course are scheduled as a standard weekly timetable.

Learning Resources

Course materials are made available in a learning and collaboration tool called Canvas which also includes reading lists and lecture recordings (where available).

Please remember that the recording of any class on a personal device requires the permission of the instructor.

Student Feedback

During the course Class Representatives in each class can take feedback to the staff responsible for the course and staff-student consultative committees.

At the end of the course students will be invited to give feedback on the course and teaching through a tool called SET or Qualtrics. The lecturers and course co-ordinators will consider all feedback.

Your feedback helps to improve the course and its delivery for all students.

Tutorials and assignments will be revised to provide more practice on the basics at the beginning of the course.

Academic Integrity

The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework as a serious academic offence. The work that a student submits for grading must be the student's own work, reflecting their learning. Where work from other sources is used, it must be properly acknowledged and referenced. This requirement also applies to sources on the internet. A student's assessed work may be reviewed for potential plagiarism or other forms of academic misconduct, using computerised detection mechanisms.

Class Representatives

Class representatives are students tasked with representing student issues to departments, faculties, and the wider university. If you have a complaint about this course, please contact your class rep who will know how to raise it in the right channels. See your departmental noticeboard for contact details for your class reps.
