## Module will run

Occurrence Teaching cycle
A Autumn Term 2019-20

## Module aims

To equip students with the necessary skills and knowledge to allow analysis of multilevel data. By means of lectures and hands-on analysis of data from real studies using the statistical software package STATA. The student is guided through a range of statistical techniques that can be used based on the nature of the outcome when the data follow a multilevel structure.

## Module learning outcomes

At the end of the module, the student should be able to:

1. Identify when to use a multilevel regression approach versus ordinary regression approach.
2. Identify different types of multilevel structures.
3. Distinguish between levels and variables and between fixed and random effects.
4. Distinguish between different outcomes and correspondingly carry out the appropriate multilevel regression.
5. Demonstrate, by example, how to formulate a multilevel model and how to interpret the results obtained from fitting the model.
6. Use multilevel modelling for the analysis of cluster randomised trials.
7. Use a statistical package to carry out analyses.

Students will be able to carry out multilevel data analysis on a number of outcomes using a statistical package and critically read research papers that use multilevel analysis.

## Module content

 Prior to commencing the module, students are expected to demonstrate knowledge of ordinary linear, logistic, and survival regression methods and ability to carry these regressions.   Subject content Revision of Generalised Linear Models Topics to include multiple linear regression, logistic regression, Poisson regression, and Survival Analysis   What is Multilevel modelling? Introduce a range of multilevel structures, e.g nesting and cross classification, with examples from real studies, introduce how to represent multilevel structures using subscripts, distinguish between levels and variables, and fixed and random effects.   Multilevel modelling for a continuous outcome Introduce the random intercept and the random slope models pointing out why standard linear regression does not work in the case of multilevel structures together with the assumptions underlying these models and sample size issues.   Multilevel modelling for a binary outcome and count data Extend the random intercept and the random slope models to the case of a binary response and count data focusing on how to interpret the models and introduce the latent variable approach in the case of binary outcome.   Multilevel modelling for time-to-event data Introduce the discrete time approach to analyse time-to-event data and extend the model to the multilevel case.   Multilevel modelling in cluster randomised trials A brief introduction to cluster randomised trials and how to analyse them using multilevel modelling also hinting to other methods used to analyse cluster randomised trials.

The University is constantly exploring ways to enhance and improve its degree programmes and therefore reserves the right to make variations to the content and method of delivery of modules, and to discontinue modules, if such action is reasonably considered to be necessary by the University. Where appropriate, the University will notify and consult with affected students in advance about any changes that are required in line with the University's policy on the Approval of Modifications to Existing Taught Programmes of Study.

## Coronavirus (COVID-19): changes to courses

The 2020/21 academic year will start in September. We aim to deliver as much face-to-face teaching as we can, supported by high quality online alternatives where we must.
