George Leckie

Senior Lecturer in Social Statistics

Short biography and research interests

George Leckie is a Senior Lecturer in Social Statistics at the Centre for Multilevel Modelling (CMM) and Graduate School of Education, University of Bristol, UK. He also holds a status-only Associate Professor position at the Graduate Department of Applied Psychology and Human Development, University of Toronto, Canada. His methodological interests are in the application and dissemination of multilevel and other latent variable models to analyse educational and social science data. His substantive interests include: school performance indicators and their associated publication in league tables; value-added models (VAMs) for measuring school and teacher effects on student achievement; and modelling rater effects on test scoring. He currently holds an ESRC Future Research Leaders grant and has previously been a co-investigator on several other ESRC grants. His research has been published in various international journals, including: Journal of the Royal Statistical Society, Series A; Journal of Educational and Behavioral Statistics; Journal of Educational Measurement; and Journal of Statistical Software. He has taught multilevel modelling short courses across Europe, Australia and US.

Full research interests

My methodological interests are in the application and dissemination of multilevel and other latent variable models to analyse educational and social science data. Particular areas of interest include multilevel analysis of non-hierarchical data (e.g., cross-classified models, multiple membership models), longitudinal data analysis (e.g., growth-curve models, latent class growth analysis, growth mixture models, dynamic models), and dyadic data analysis (e.g., actor-partner interdependence model, social relations model).

My substantive interests in educational research include: school performance indicators and their associated publication in league tables; value-added models (VAMs) for measuring school and teacher effects on student achievement; modelling rater effects on test scoring; and analysing neighbourhood, school and family effects on child outcomes. I also often collaborate with co-authors working in other disciplines, including: anthropology, economics, sociology, and psychology.

My statistical software interests are in developing runmlwin and runmixregls, commands to fit multilevel models in the MLwiN and the MIXREGLS software from within Stata.

Full biography

George Leckie is a Senior Lecturer in Social Statistics at the Centre for Multilevel Modelling (CMM) and Graduate School of Education (GSOE), University of Bristol, UK. He also holds a status-only Associate Professor position at the Graduate Department of Applied Psychology and Human Development, University of Toronto, Canada.

Previously, George held research positions at the Centre for Market and Public Organisation, Department of Economics, University of Bristol and have been a visiting fellow at Cornell University, UCL Institute of Education London, Queensland University of Technology, University of York, and VU University Amsterdam.

George joined CMM in 2005, initially working on the ESRC-funded LEMMA 1 grant (2005-2008). He was a co-investigator on the ESRC-funded LEMMA 2 (2008-2011) and e-Stat (2009-2012) grants and is currently a co-investigator on the ESRC-funded LEMMA 3 (2011-2015) and eBooks (2013-2016) grants. He holds an ESRC Future Research Leaders Grant (2013-2015).

His ongoing research (with Professor Harvey Goldstein), on the statistical limitations of school league tables, has received considerable attention in the press; including: BBC Radio 4, Financial Times, The Telegraph, and The Times Educational Supplement.

His current teaching commitments include running three PhD short courses on the Advanced Quantitative Methods pathway of the ESRC South West Doctoral Training Centre (SWDTC): (1) Introduction to Stata, (2) Review of Linear Regression Using Stata, and (3) Multilevel Modelling Using Stata. He also second supervises three PhD students and is a Fellow of the Higher Education Academy.

He often teachs a range of short courses on multilevel modelling to academic and other researchers: Belfast, Brisbane, Bristol, Brussels, Cincinnati, Dublin (Centre for Longitudinal Studies in Ireland), Dublin (Royal College of Surgeons, Ireland), Dublin (University College Dublin), Essex, Giessen, Oxford, London, Paris (Organisation for Economic Cooperation and Development), Southampton, Sydney, Tuebingen, and Zurich. I author an extensive set of multilevel modelling training materials for the LEMMA Multilevel Modelling Online Course.

He plays an active role in the Royal Statistical Society. Currently he sits on the Social Statistics Section committee and the Professional Development Centre committee. Since 2008, he has taught (with Professor Harvey Goldstein) an annual two-day course on multilevel modelling for the society's Short-course Programme. He has published in the society's Series A (Statistics in Society) journal and Significance magazine and has peer reviewed for Series A and Series C. He has presented regularly at the society's annual conference and at various society local group meetings.

He has worked or advised on a range of government and other external projects: Catholic University of Portugal, Colombian Evaluation Institute, Higher Education Academy, King’s College London (MRC grant), National Center for Educational Achievement (NCEA) / ACT testing company, National Assessment Agency, Pearson Education, Rand Europe, The Times and Sunday Times Data Analysis Team, University of Birmingham (DoH grant), University of Oxford (Ofqual grant).

He co-runs the DfE funded PLUG series of workshops.
