The Centre for Multilevel Modelling (CMM) is a research centre based at the University of Bristol

CMM researchers are drawn from the Graduate School of Education, Bristol Veterinary School and School of Geographical Sciences. Multilevel Modelling is a University Research Theme. We collaborate with a range of researchers working with multilevel models.

Multilevel Modelling is one of the basic techniques used in quantitative social science research for modelling data with complex hierarchical structures. The Multilevel Modelling research theme focuses on producing new statistical methods for tackling research questions, developing new software for implementing this methodology and disseminating these techniques to the national and international social science community.

We develop new statistical methodology, implemented in software to address unsolved issues in quantitative modelling of social processes.

Interrelationships between housing transitions and fertility in Britain and Australia

expand...

The principal aim of this project is to examine the extent to which housing transitions and residential location choice are influenced by fertility outcomes such as the birth of a(nother) child or a child reaching primary or secondary school age, allowing for the effects of other social processes such as union formation and dissolution and employment changes.

Multilevel Modelling of the Government's New School Performance Measures, 'Floor Standards' Target and 'Narrowing the Gap' Priority

expand...

Each year, the Government publishes school performance tables that report the achievement and progress of pupils in English secondary schools. In the 2011 tables, the Government introduced a number of changes. These changes have important implications and it is therefore imperative that they are critically reviewed and that innovative techniques are developed and applied to explore potential improvements to the accuracy, usefulness and communication of school performance tables.

This grant will do this by pursuing a programme of methodological and substantive research using multilevel modelling, and based on secondary analyses of the Government’s highly detailed pupil and school level performance data which underlie their tables.

The use of interactive electronic-books in the teaching and application of modern quantitative methods in the social science

expand...

The aims of this project are to provide computer-assisted support to increase the skills and understanding of quantitative principles and techniques of researchers in UK social science, and to create innovative tools for reproducible research.
