LEMMA was an interdisciplinary node specialising in the analysis of data with complex structure that mirrors substantive research questions. Such complex structure includes household and family data, contextual, neighbourhood and area effects, spatial analytical models, longitudinal data structures, event-duration models, and mover-stayer models.
LEMMA workin Phase 1 included:
1. Important and much-needed methodological developments in the specification and estimation of multilevel models including the analysis of non-hierarchical structures, complex dependencies between structures and latent-class models; all these developments will be implemented in appropriate software. An unrestricted version of the MLwiN is software freely available to the ESRC ‘constituency’ for the lifetime of the project;
2. A variety of integrated flagship projects using this methodology to research important social science questions; these will not only serve to demonstrate the methodological developments but will also be substantively important in their own right.
3. Extensive capacity building and research training in the analysis of data with complex structure; in addition to a series of face to face workshops we will establish a multilevel modelling virtual learning environment(VLE) which is designed to initiate, develop, and support geographically-dispersed researchers.
LEMMA was based at the Centre for Multilevel Modelling at the University of Bristol.
