DESCRIPTION - summary of the module content

Statistical models help us to describe and predict the real world, and are used in sectors as diverse as finance, insurance, economics, marketing, pharmaceuticals, sport, environment and government to name only a few. Statistical inference is the way that we use data and other information to learn about and apply our models. This module introduces you to some of the main approaches to statistical inference and explains their associated procedures. It is designed for students who want to understand the ideas and mathematical theory that lie behind many modern statistical methods. The module establishes key theoretical concepts and results alongside explanations of their practical purpose and application. We will use computer simulations to illustrate basic concepts and as a tool for comparing procedures. You will gain practical experience with the methods through a series of worked examples and exercises.

Prerequisite module: ECM2709 or equivalent

 

AIMS - intentions of the module

This module aims to help you to develop a thorough understanding of statistical inference from a frequentist perspective. This includes understanding the underlying concepts, the mathematical theory, and how to apply the inferential methods to a range of statistical models. Such understanding is important for any job that involves conducting statistical investigations.

.

INTENDED LEARNING OUTCOMES (ILOs) (see assessment section below for how ILOs will be assessed)

On successful completion of this module, you should be able to:

Module Specific Skills and Knowledge:
1 demonstrate an understanding of the purpose of statistical inference, different approaches to statistical inference, and the key theoretical results and inferential procedures associated with these approaches;
2 apply these procedures to draw inferences about parametric statistical models, and compare different procedures critically.
Discipline Specific Skills and Knowledge:
3 demonstrate an understanding of the ways in which statistical inferential procedures and their performances may differ;
4 demonstrate an understanding of inferential concepts integral to statistical science;
5 progress to study a wider range of statistical inferential approaches in more detail.
Personal and Key Transferable/ Employment Skills and  Knowledge:
6 demonstrate an understanding of key mathematical arguments, statistical concepts and practical issues important for advanced study, application and development of statistical science;
7 use the statistical programming environment 'R' to implement generic inferential procedures and to conduct simulation studies.
 

SYLLABUS PLAN - summary of the structure and academic content of the module

1. Classical Inference. The principles and methods of classical frequentist inference are explained. These include point estimators, bias and efficiency; hypothesis tests, the Neyman-Pearson Theorem and uniformly most powerful tests; and confidence sets and their construction from hypothesis tests.

2. Likelihood Inference. Inferential approaches based on the likelihood are introduced. These include maximum likelihood estimators and their asymptotic properties; likelihood-based hypothesis tests and confidence sets; and pseudo-likelihoods.

3. Resampling. Inferential approaches based on resampling are introduced. These include Monte Carlo and bootstrap tests; the jackknife and bootstrap estimates of bias and variance; and bootstrap confidence sets.

RE-ASSESSMENT NOTES

If a module is normally assessed entirely by coursework, all referred/deferred assessments will normally be by assignment.


If a module is normally assessed by examination or examination plus coursework, referred and deferred assessment will normally be by examination. For referrals, only the examination will count, a mark of 40% being awarded if the examination is passed. For deferrals, candidates will be awarded the higher of the deferred examination mark or the deferred examination mark combined with the original coursework mark.
