摘要翻译:
本文证明了Citet*{pearl1995testability}中关于检验隐变量模型中工具变量有效性的猜想。这意味着在内源性治疗连续分布的情况下,仪器有效性不能被检验。这与处理离散时仪器有效性的经典测试结果形成鲜明对比。然而,在模型上施加弱的结构假设,如可观察变量之间的连续性,可以在连续设置中重新建立理论可测性。

英文摘要:
This note presents a proof of the conjecture in \citet*{pearl1995testability} about testing the validity of an instrumental variable in hidden variable models. It implies that instrument validity cannot be tested in the case where the endogenous treatment is continuously distributed. This stands in contrast to the classical testability results for instrument validity when the treatment is discrete. However, imposing weak structural assumptions on the model, such as continuity between the observable variables, can re-establish theoretical testability in the continuous setting.
