Outlier robust inference in the instrumental variable model with applications to causal effects
Outlier robust inference in the instrumental variable model with applications to causal effects
Summary The AndersonāRubin (AR) test is an important method that allows for reliable inference in the instrumental variable model when the instruments are weak. Yet, the robustness properties of this test have not been formally studied. As it turns out that the AR test is not robust to outliers, we ā¦
