Presentation: Machine Learning for Causal Inference in Randomized and Observational Studies Abstract: Modern causal inference increasingly incorporates flexible machine learning methods to improve efficiency and robustness, but valid inference requires that these methods respect the structure of the underlying study design. This dissertation develops machine-learning-assisted causal inference methods for randomized and observational studies, with an emphasis on design-based validity, weak-null hypothesis testing, and covariate balance. The first dissertation project develops Fisher randomization tests for Neyman’s weak null hypothesis that can incorporate flexible predictions of potential outcomes. We construct a studentized augmented inverse probability weighted statistic and study its sampling and permutation distributions under a finite-population framework, with the goal of improving power while preserving asymptotic type-I error control.

General Exam - Min Haeng Cho

Presentation: Essays in Causal Inference Abstract: We study several questions when estimating a causal effect in an observational study or randomized clinical trial. In the first project, we introduce a non-bipartite, template matching algorithm that strengthens an instrumental variable while maintaining fidelity to the original study cohort for an observational study. We then study randomization-based and biased randomization-based inference for partial identification bounds of the sample average treatment effect. In the second project, we formalize an existing win ratio estimand, a popular method used to evaluate composite outcomes in randomized clinical trials, under the potential outcomes framework and introduce an alternative win ratio estimand. We compare the two estimands using simulations and propose inferential methods. In the third project, we develop a joint modeling framework to simultaneously estimate the latent longitudinal biomarker trajectory and a causal estimand. We specify identification… Event interval: Single day event. Campus location: Hans Rosling Center for Population Health (HRC). Online Meeting Link: https://washington.zoom.us/j/99356085134.

Biostatistics Seminar: Surrogate-powered Causal Inference with Censored Outcomes

Speaker: Yaroslav Mukhin, PhD, Assistant Research Professor, Center for Data Science for Enterprise and Society, Cornell University Title: Surrogate-powered Causal Inference with Censored Outcomes Abstract: Clinical trials with survival endpoints lose information when participants are censored before death is observed. We develop target-preserving estimators that use posttreatment disease history, such as recurrence or progression, to recover information lost to censoring for marginal survival and restricted mean survival effects. The difficulty is that the intermediate event is downstream of treatment: naive adjustment can change the causal estimand, and the useful information enters only through the observed coarsening. We derive observed-data influence functions with and without recurrence history and obtain an exact gain identity. The identity shows that efficiency improvement is driven by the censoring hazard, the split of the alive risk set into recurrence states, and the residual-survival separation… Event interval: Single day event.
