Centre for Multilevel Modelling (CMM)

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, The School of Veterinary Science and the the School of Geographical Sciences. CMM is part of the The Bristol Institute of Public Affairs (BIPA). Multilevel Modelling is a University Research Theme. We collaborate with a range of researchers working with multilevel models.

Our research >>

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