Thus\ , the credibility of a study crucially depends on the extent that its assu mptions can be defended. The purpose of this talk is to give a high-level overview of how the statistical literature on sensitivity analysis evolved from its inception in the debate about smoking and lung cancer in the 195 0s. I will review the first sensitivity analysis by Cornfield in 1959\, th e model and methodology based on randomization inference proposed by Rosen baum\, and other related literature. A recent emerging trend is to formula te sensitivity analysis for observational studies as a stochastic programm ing problem\, which provides a unified conceptual framework for many exist ing models and methods. I will review some recent progress in this area an d highlight the variety of theoretical\, methodological\, and practical di fficulties involved in this framework. Part of this talk is based on joint work with Yao Zhang and Tobias Freidling.\n LOCATION:https://researchseminars.org/talk/UEA_mth/1/ END:VEVENT END:VCALENDAR
