Chien-Pai Han

Chien-Pai Han (December 17, 1936 - September 1, 2020) was an American statistician known for his contributions to statistical inference, multivariate analysis, discriminant analysis, and sample survey methodology. Han held faculty positions at Iowa State University (1967-1982) and the University of Texas at Arlington (1982-2017). where he studied under the supervision of Arthur P. Dempster. where he contributed to research and teaching in mathematical statistics.

Research contributions Han's research contributions spanned multiple areas of statistical theory and methodology. His early work focused on discriminant analysis, particularly the distribution of discriminant functions when covariance matrices have special structures. His work in this area provided theoretical foundations for classification problems in multivariate analysis.

Han made contributions to survey sampling theory, including work on double sampling with partial information on auxiliary variables estimation in random effects models,
