Statistical Inference for Bivariate Functional Causal Discovery
Shreya Prakash, Fan Xia, Elena A. Erosheva
Causal discovery methods aim to determine the causal direction between variables using observational data. Functional causal discovery methods rely on structural and distributional…
Causal Discovery via Statistical Power (CDSP)
Shreya Prakash, Fan Xia, Elena A. Erosheva
Causal discovery methods aim to infer causal direction from observational data. Functional causal discovery approaches use structural asymmetries to identify causal directionality…
Robust and Efficient Semiparametric Inference for the Stepped Wedge Design
Fan Xia, K. C. Gary Chan, Emily Voldal +3
Stepped wedge designs (SWDs) are increasingly used to evaluate longitudinal cluster-level interventions but pose substantial challenges for valid inference. Because crossover times…
Factors affecting power in stepped wedge trials when the treatment effect varies with time
Avi Kenny, Emily C. Voldal, Fan Xia +3
Stepped wedge cluster randomized trials (SW-CRTs) have historically been analyzed using immediate treatment (IT) models, which assume the effect of the treatment is immediate after…
A Diagnostic Tool for Functional Causal Discovery
Shreya Prakash, Fan Xia, Elena Erosheva
Causal discovery methods aim to determine the causal direction between variables using observational data. Functional causal discovery methods, such as those based on the Linear No…
Analysis of stepped wedge cluster randomized trials in the presence of a time-varying treatment effect
Avi Kenny, Emily Voldal, Fan Xia +2
Stepped wedge cluster randomized controlled trials are typically analyzed using models that assume the full effect of the treatment is achieved instantaneously. We provide an analy…
Defining and Estimating Subgroup Mediation Effects with Semi-Competing Risks Data
Fei Gao, Fan Xia, Kwun Chuen Gary Chan
In many medical studies, an ultimate failure event such as death is likely to be affected by the occurrence and timing of other intermediate clinical events. Both event times are s…
