Summary

Anders Skrondal's current positions are:

 Skrondal started his career as a Research Fellow in the Department of Economics and as a Researcher in the Department of Biostatistics, both at the University of Oslo. His Doctor Philos thesis in Statistics was awarded the 1997 Psychometric Society Dissetation Prize, judged on "the level of originality in the ideas and techniques, the possible applications and their treatment, and potential impact". He was subsequently awarded a Research Council of Norway Postdoctoral Fellowship which was spent at the University of London and The University of Manchester. After returning to Norway, Skrondal became a Senior Researcher and subsequently Head of the Biostatistics Group at the Norwegian Institute of Public Health. He recently served as Professor of Statistics, Department of Statistics, London School of Economics (LSE) and Director of the LSE Methodology Institute.

Anders Skrondal's research interests include topics in statistics, biostatistics, social statistics and psychometrics. Recently, he has concentrated on collaborative work on the development of the Generalized Linear Latent and Mixed Model (GLLAMM) framework. Outcomes of this project include numerous papers published in statistical, biostatistical, psychometric and econometric journals as well as two recent bestselling books. Skrondal is involved in numerous collaborative projects within medical, social and behavioural research. He has published in about 50 different peer-reviewed journals.

Skrondal is an Editor of the journal Statistical Methods in Medical Research and the Chapman & Hall/CRC book series Statistics in the Social and Behavioral Sciences. He is an elected member of the International Statistical Institute, the editorial council of Psychometrika and the Research Section Committee of the Royal Statistical Society (selecting papers to be read for the Society). Anders Skrondal has served on scientific committees for international conferences, taken part in expert panels evaluating academic institutions, and reviewed research proposals and/or research programs for numerous funding bodies in the US and Europe. He was recently awarded the title of Honorary Professor from the London School of Hygiene and Tropical Medicine, a world leader in epidemiology.

    GLLAMM

    Generalised Linear Latent And Mixed Models (GLLAMMs) include a large variety of multilevel latent variable models including generalised linear mixed models, multilevel factor models or item response models, multilevel structural equation models and latent class models.

    The Stata program gllamm estimates GLLAMMs by maximum likelihood using adaptive quadrature. The software has been used in numerous books and in articles in over 300 different journals indexed in the ISI Web of Science. Users are from many disciplines including medicine, biology, sociology, political science, economics, veterinary science, psychology, law, education, and statistics. The gllamm manual has been downloaded more than 20000 times since October 2004.
