ST220 Introduction to Mathematical Statistics
Please note that all lectures for Statistics modules taught in the 202223 academic year will be delivered on campus, and that the information below relates only to the hybrid teaching methods utilised in 202122 as a response to Coronavirus. We will update the Additional Information (linked on the right side of this page) prior to the start of the 2022/23 academic year.
Throughout the 202122 academic year, we will be adapting the way we teach and assess your modules in line with government guidance on social distancing and other protective measures in response to Coronavirus. Teaching will vary between online and oncampus delivery through the year, and you should read the additional information linked on the right hand side of this page for details of how this will work for this module. The contact hours shown in the module information below are superseded by the additional information.You can find out more about the University’s overall response to Coronavirus at: https://warwick.ac.uk/coronavirus.

ST22012 Introduction to Mathematical Statistics
Introductory description
This module runs in Term 1 and is optional for students in their second year and from outside the Statistics department. It is of particular relevance to students who may be interested in taking third year Statistics modules.
Students from outside Statistics and not in their second year should take 'ST22612 Introduction to Mathematical Statistics' instead, which is identical to this module.
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 nonStatistics 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: Chisquared, 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 pvalues.
 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.
