In studies based on electronic health records (EHR), the frequency of covariate monitoring can vary by covariate type, across patients, and over time. This can lead to major challe…
Conducting Simulations in Causal Inference with Networks-Based Structural Equation Models
Oleg Sofrygin, Romain Neugebauer, Mark J. van der Laan
The past decade has seen an increasing body of literature devoted to the estimation of causal effects in network-dependent data. However, the validity of many classical statistical…
Targeted Learning with Daily EHR Data
Oleg Sofrygin, Zheng Zhu, Julie A Schmittdiel +4
Electronic health records (EHR) data provide a cost and time-effective opportunity to conduct cohort studies of the effects of multiple time-point interventions in the diverse pati…
