ST220-12 Introduction to Mathematical Statistics
Introductory description
This module runs in Term 1 and is optional for students from outside the Statistics department. It is of particular relevance to students who may be interested in taking third year Statistics modules.
This module is not available to students who have their home department in Statistics, who take equivalent modules.
Prerequisites: ST111 Probability A and ST112 Probability B
Leads to: Many ST3 modules.
Module aims
This module is designed for students in the Mathematics, Computer Science and other non-Statistics departments. It will introduce the main ideas of statistical inference emphasising the use of likelihood for estimation and testing. These ideas are fundamental to the use of statistics in modern applications such as mathematical finance, telecommunications, bioinformatics as well as more traditional areas such as insurance, engineering and the social sciences.
Outline syllabus
This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.
- Standard families of Probability distributions: Binomial, Geometric, Poisson, Exponential, Gamma, Gaussian.
- The weak law of large numbers and central limit theorem.
- The Multivariate Gaussian distribution. Orthogonality and Independence for jointly Gaussian random variables.
Distributions derived from the Gaussian: Chi-squared, t and F. - The notion of a parametrized Statistical model, and examples.
- Likelihood including maximum likelihood estimates and use of likelihood ratios to compare hypotheses.
- The repeated sampling principle: bias and MSE, confidence intervals and p-values.
- Fisher's theorem on Gaussian sampling, and its extension to linear regression.
Learning outcomes
By the end of the module, students should be able to:
- Understand more advanced notions of probability needed in mathematical statistics including properties of multivariate Gaussian distributions, the law of large numbers, and the central limit theorem.
- Understand the main notions of statistical inference including a (parametrized) statistical model, an estimator and its sampling distribution, and hypothesis tests.
- Be able to calculate maximum likelihood estimators in a variety of examples. Be able to derive properties of sampling distributions of estimators in a variety of examples, and thereby construct confidence intervals.
- Be able to use likelihood ratios to construct hypothesis tests in a variety of examples including the classical t and F tests.
