Ke-Hai Yuan's research has been around developing better or more valid methods for analyzing messy data or nonstandard samples in social and behavioral sciences. Most of his work is on factor analysis, structural equation modeling, and multilevel modeling. He has also worked on correlations, regression, combining effect sizes, mean comparison and power, classical and modern testing theory, statistical computation, and estimating equations. His teaching interests include psychometric theory, structural equation modeling, item response theory, missing data, asymptotics and simulation based research methodology.

Agung SantosoAgung is a fourth year students in the PhD program and a Fulbright grantee from Indonesia. He worked on using quantile regression on real data for his M.A. and currently is extending quantile regression application to mediation analysis. He is also working on the application of equivalence testing, for example to select anchor items for differential item functioning. Child and adolescent development, and teaching effectiveness are substantive topics he is also interested.
