Calibrated Bayesian inference for overall and subgroup-specific causal effects in stepped-wedge cluster-randomized trials

Stepped-wedge cluster-randomized trials (SW-CRTs) randomly assign clusters to sequences that determine when each cluster switches from control to intervention. Conventional Bayesian analyses of SW-CRTs report treatment effect coefficients from a working outcome model, but under model misspecification or informative clu...

Sharp bounds for population and principal effects under latent sequential ignorability

Treatment decisions are often sequential and depend on information absent from the recorded history. Latent sequential ignorability models such assignment by assuming that baseline covariates and principal strata, defined by joint potential intermediate responses, account for confounding of later treatment. For two tre...
