MATH3012 Statistical Methods II

Module Overview

The module Statistical Methods I covers in detail the theory of linear regression models, where explanatory variables are used to explain the variation in a response variable, which is assumed to be normally distributed. However, in many practical situations the data are not appropriate for such analysis. For example, the response variable may be binary, and interest may be focused on assessing the dependence of the probability of 'success' on potential explanatory variables. Such techniques are important in many disciplines such as finance, market research and medicine. Alternatively, a variety of biological and social science data are in the form of cross-classified tables of counts, called contingency tables. The structure of such tables can be examined to determine the pattern of interdependence of the cross-classifying variables.

Aims and Objectives

Module Aims

To cover the theory and application of generalised linear models. This is an extremely broad class of statistical models, which incorporates the linear regression models studied in Statistical Methods I, but also allows binary or count data to be modelled coherently. A series of flexible estimation and model comparison procedures are introduced and used to analyse appropriate data. The interactive statistical computer language R or S-Plus is used throughout

Learning Outcomes

Learning Outcomes

Having successfully completed this module you will be able to:

  • Analyse binary and binomial data using logistic regression models, and other generalised linear models where appropriate
  • Estimate coefficients of a generalised linear model using maximum likelihood, interpret the estimates and calculate confidence intervals for the estimates
  • Recall the definition of a generalised linear model;
  • Use exponential family and likelihood theory to derive important results for generalised linear models
  • Interpret log-linear models in terms of independence and conditional independence
  • Compare generalised linear models using likelihood ratio tests
  • Analyse data appropriately using R or S-Plus
  • Assess goodness of fit of a generalised linear model using deviance and residuals
  • Use generalised linear models to evaluate predictions and assess the corresponding uncertainty


The module consists of 11 weeks of lectures. The topics for the weeks are roughly as follows: Week 1: Introduction. Revision of distribution and motivation for GLM. Week 2-3: Revision of likelihood based inference/linear models. Weeks 4-8: GLMs: theory and application. Weeks 9-11: Log-Linear models and contingency tables. Likelihood based statistical theory will also be introduced as and when required
