ST21812 Mathematical Statistics Part A
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.
Prerequisite: 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 Chisquared, 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.
