MATH6153 Statistical Theory and Linear Models

Module Overview

This module provides an intensive introduction to, or revision of, essential ideas in developing statistical theory. Firstly, basic statistical models are reviewed along with their properties. Then the transformation method for random variables is introduced to derive standard statistical distributions. The middle part of the module concerns the theory for making statistical inference, including methods such as maximum likelihood estimation and likelihood ratio tests, and an introduction to Bayesian methods. Finally, the theory of linear models is introduced, which will include multiple linear regression models and mixed effects models as examples.   

Aims and Objectives

Aim

Having successfully completed this module, you will be able to:

  • Standard univariate statistical models and their properties.
  • Theory of estimation and significance testing, and know when particular tests should be applied.
  • Bayesian inference methods for conjugate priors, prediction method and marginal likelihood.
  • Theory of linear statistical models.

Syllabus

  • Univariate distributions: Common standard distributions and their properties.
  • Estimation: Unbiasedness, Method of Moments, 
  • Likelihood - score functions, information, maximum likelihood estimators, Cramer-Rao Inequality.
  • Confidence intervals: Asymptotic methods and interpretations.
  • Hypothesis testing: Neyman-Pearson Lemma and the Generalised likelihood ratio tests.
  • Bayesian methods for conjugate priors, prediction method and marginal likelihood.
  • Theory of linear models:
    • Simple and multiple linear regression,
    • The principle of least squares and least squares estimators,
    • Linear hypothesis testing,
    • Properties of least squares estimators,
    • Model selection.
