Talk by Leonard Henckel, Copenhagen Causality Lab, KU (University of Copenhagen): Graphical Tools for Selecting Conditional Instrumental Set

<p>Title: Graphical Tools for Selecting Conditional Instrumental Sets</p><p>Abstract: We consider the problem of how to select conditional instrumental set in order to consistently and accurately estimate total causal effects using the two-stage least squares estimator in linear structural equation models. We first graphically characterize the class of conditional instrumental sets that ensure a consistent estimator; a class we refer to as valid conditional instrumental sets. Equipped with this definition, we provide three graphical tools for selecting more accurate valid conditional instrumental sets: First, a graphical criterion that for certain pairs of valid conditional instrumental sets identifies which of the two corresponding estimators has the smaller asymptotic variance. Second, a forward algorithm that greedily adds covariates that reduce the asymptotic variance to a valid conditional instrumental set. Third, a valid conditional instrumental set for which the corresponding estimator has the smallest asymptotic variance we can ensure with a graphical criterion.</p>
