MATH3091 Statistical Modelling II
Module Overview
The module Statistical Modelling II 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
Learning Outcomes
Learning Outcomes
Having successfully completed this module you will be able to:
- Derive properties of the exponential family and determine whether a given distribution is a member of the exponential family.
- Apply likelihood theory to conduct inference in generalised linear models: estimate parameters, construct confidence intervals, make predictions and compare candidate models.
- Fit appropriate generalised linear models to data using R and interpret the fitted models.
- Interpret log-linear models in terms of independence and conditional independence.
Syllabus
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 and linear models. Weeks 4-8: GLMs: theory and application. Weeks 9-11: Log-Linear models and contingency tables.
