Roderick Little

Email Address: 

Research Professor, ISR; Richard D. Remington Distinguished University Professor of Biostatistics, School of Public Health; Professor of Statistics, LS&A

Little received a PhD in statistics from Imperial College, London University in the United Kingdom. His current research interests involve analysis of data with missing values; analysis of repeated measures data with drop-outs; survey sampling, focused on model-based methods for complex survey designs that are robust to misspecification and compared to the resulting inferences to classical methods based on the randomization distribution; and applications of statistics to epidemiology, public health, psychiatry, sample surveys in demography and economics, and medicine. From 2010-12 he served as the inaugural Associate Director for Research and Methodology and Chief Scientist at the U.S. Census Bureau.

Research Interests

Bayesian Survey Inference, Survey Nonresponse, Missing Data, Applications of Statistics in Public Health, Medicine, Government.
