# STAT6108 Analysis of Hierarchical (Multilevel & Longitudinal) Data

## Module Overview

This module introduces students to the main statistical modelling approaches that can handle hierarchical data structures. The module has mainly an applied scope where basic theory is introduced to ensure understanding. Practical computer sessions using MLwiN and R are conducted where appropriate.

### Aims and Objectives

#### Learning Outcomes

##### Learning Outcomes

Having successfully completed this module you will be able to:

• Contrast the main statistical models available for the analysis of hierarchical and longitudinal data.
• Apply multilevel and marginal models for the analysis of hierarchical and longitudinal data.
• Interpret the results from these statistical analyses in a non-technical language.
• Understand the potential of more advanced elements, such as contextual variables and heterogeneous covariance structures for the analysis of hierarchical and longitudinal data.
• Recognise the basic statistical theory underpinning multilevel and marginal models.

### Syllabus

• Hierarchical data structures • Multilevel models: random intercepts and random slopes; contextual variables, cross-level interactions and heterogeneous variance structures • Model building: estimation; testing; diagnostic checking (specification issues and residual analysis); model selection • Longitudinal data structures • Multilevel and Marginal models for longitudinal data • Models for hierarchical and longitudinal binary response data The module will integrate the theory with practical application using MLwiN and R.

### Learning and Teaching

#### Teaching and learning methods

Teaching will be delivered by a mixture of synchronous and asynchronous online methods, which may include lectures, quizzes, discussion boards, workshop activities, exercises, and videos. A range of resources will also be provided for further self-directed study. Face-to-face teaching opportunities will be explored depending on circumstances and feasbility.
