Abstract: A Bayesian nonparametric using enriched Dirichlet process mixtures is proposed to model the observed data in EHRs with an ultimate goal of causal inference. Missing data (in confounders and the outcome) is allowed to be nonignorable and auxiliary information in the EHR can be exploited to move the missingness closer to MAR. We illustrate the approach via simulations and a data example.
