In causal inference and censored data methods, double robust estimators such as Targeted Minimum Loss-based estimation require the specification of two model components. Estimation will be consistent under the correct specification of either nuisance component, conditional on a sufficient set of confounding variables. However, this class of estimators also has a collaborative robustness property that allows for consistent effect estimation in a wider class of settings. This property can be useful for guiding both manual and automated variable selection. We describe this class of estimators in single time point and longitudinal exposure settings, describe a cohesive approach to variable selection in causal inference, and illustrate the performance of data-adaptive learning algorithms for the nuisance models.
About the Presenter
Mireille Schnitzer is an Assistant Professor of Biostatistics at the University of Montreal. Mireille received her PhD in Biostatistics from McGill University in 2012 and was a postdoctoral research fellow at the Harvard T.H. Chan School of Public Health in 2013. She also had the opportunity to study causal inference at U.C. Berkeley and the University of Pennsylvania as a visiting student. Mireille's current research interests are causal inference methodology in the fields of pharmacoepidemiology and population surveillance, the usage of electronic medical databases, semiparametric efficient estimation in longitudinal and survival settings, and meta-analysis. Mireille currently holds NSERC Discovery and Accelerator grants, a CIHR New Investigator Salary Award and is also funded by the Fonds de Recherche du Québec, Santé and by the Faculté de pharmacie at Université de Montréal.
