About
Dr. Hansen's research develops methods that aim to sharpen comparisons of subjects receiving an intervention to subjects receiving a control condition, particularly nonrandomized comparisons, and to improve communication and understanding of remaining uncertainties regarding effects of the intervention. He writes on statistical and computation issues related to matching, on diagnostics for randomized studies and for matched observational studies, on sensitivity analysis, and on propensity scores and related methods of dimension reduction sensitivity analysis, and he is a co-developer of R libraries for optimal matching and associated diagnostics.
