Description

Bayesian Inference

STAT314 and STAT461 introduce theory and application of Bayesian Inference. Due to recent advances in computing and to the existence of some relatively user-friendly software Bayesian methods are becoming more and more popular in many applied fields of study, including epidemiology, bioinformatics, ecology and archaeology. This course will cover the basic of Bayesian theory as well as introduce computing methods necessary for implementation of this theory in practice. In addition to generalised linear regression models, analysis of variance and basic tests, for which the results of Bayesian inference will be compared with those for the classical frequentist results, the course will demonstrate the attractive flexibility and multifacetedness of Bayesian methods considering such problems as threshold analysis, and Poisson change-point problems among others.

Topics that are usually covered include:
• Bayes’ Inverse Probability Formula and Bayes’ Theorem. The concepts of prior and posterior distributions. Posterior predictive distribution. Various types of prior distributions.
• Bayesian model comparison and Bayesian model averaging.
• Numerical tools for Bayesian estimation: Markov Chain Monte Carlo (MCMC) methods, Gibbs sampler and Metropolis-Hasting sampler.
• Bayesian inference on linear regression models, generalised linear models, and mixed-effects models.
• Treatment of missing data and latent parameters
The statistical computations will be performed using a combination of WinBUGS (a software for Bayesian inference) and R (a statistical software package). Prior knowledge of WinBUGS is not required. Prior knowledge of R is desirable.

Goal of the Course:
To teach students to apply Bayesian inference methods to a range of common problems.

Learning Outcomes

  • The course will:
  • introduce the foundations of Bayesian inference
  • introduce the use of stastical software WinBUGS and R.
  • introduce numerical algorithms required for practical Bayesian inference.
  • demonstrate application of Bayesian inference to a wide range of common problems
  • provide some comparison of Bayesian inference to the classical frequentist methods
  • give you experience in writing scientific and technical reports

    You will be able to:
  • choose appropriate method for analysis of your dataset
  • use WinBUGS or R to perform your analysis
  • be able to interpret the analysis results in such a way that a non-user of statistics can understand
  • write a scientific and technical report.

Prerequisites

Assessment

Assessment Due Date Percentage 
Assignments 20%
Project 50%
Written Examination 30%


There will be two lectures and one computer lab per week for this course. Attendance at lectures and computer labs is mandatory because supervised instruction is essential for understanding the course material.

The continual assessment consists of a series of exercises that must be submitted at specified times throughout the course. These exercises and their timings are designed to help you keep up with the course material. They also allow the lecturer to monitor progress and to provide assistance in a timely manner when needed.

There will be three tests, one every four weeks, but no final exam.

Textbooks / Resources

Course materials will be provided and no textbook is needed. After enrolling in the course, you will be able to access materials from the course web page in Learn at: http://www.learn.canterbury.ac.nz/

Students who have not used the R software before can refer to the following e-book available from the UC Library:

A Beginner’s Guide to R, by Zuur, Ieno and Meesters (Springer, 2009).
