# Module Catalogue

Throughout the 2021-22 academic year, we will be prioritising face to face teaching as part of a blended learning approach that builds on the lessons learned over the course of the Coronavirus pandemic. Teaching will vary between online and on-campus delivery through the year, and you should read guidance from the academic department for details of how this will work for a particular module. You can find out more about the University’s overall response to Coronavirus at: https://warwick.ac.uk/coronavirus.

##### Introductory description

This module runs in Term 1 and is core for students with their home department in Statistics and not available for students from other departments.

Pre-requisite: ST115 Introduction to Probability.

##### Module aims

To develop more advanced probabilistic methods that are used in Statistics.
The module builds the necessary probability background for mathematical statistics. It covers topics such as multivariate probability distributions, conditional probability distributions and conditional expectation, multivariate normal distribution, convergence of sequences of random variables.

##### 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.

Discrete and continuous multivariate distributions. Marginal distributions.
Jacobian transformation formula.
Conditional distributions, conditional expectation and properties.
Moment generating functions for multivariate random variables.
Multivariate Gaussian distribution and properties.
Distributions related to Gaussian distribution: the Chi-squared, Student's and Fisher distributions.
Convergence in distribution, convergence in probability and almost sure convergence. Examples.
Laws of large numbers.
Central limit theorem.

##### Learning outcomes

By the end of the module, students should be able to:

• Understand more advance notions of probability needed in mathematical statistics including properties of multivariate Gaussian distributions, the law of large numbers, and the central limit theorem.
• Be able to calculate probabilities and expected values in more complex and sometimes multidimensional contexts.
• To be able to manipulate mathematical statements regarding the limiting behaviour of random sequences.
##### Subject specific skills

Mathematical, analytical, problem solving

##### Transferable skills

Analytical, problem solving, investigative skills, communication, good working habits
