摘要翻译:
本文研究了两个标量估计之间的局部渐近关系。我们将目标估计对控制估计的灵敏度定义为目标泛函相对于控制泛函梯度方向的方向导数。根据模型流形上的信息度量,灵敏度是正则有效估计量的渐近协方差。模型流形上根据一般策略度量的灵敏度可以由正则有效估计量的影响函数得到。策略敏感性具有局部反事实解释,其中ceteris paribus向反事实分布的变化由模型流形上的控制参数和黎曼度量的组合指定。

英文摘要:
This paper studies local asymptotic relationship between two scalar estimates. We define sensitivity of a target estimate to a control estimate to be the directional derivative of the target functional with respect to the gradient direction of the control functional. Sensitivity according to the information metric on the model manifold is the asymptotic covariance of regular efficient estimators. Sensitivity according to a general policy metric on the model manifold can be obtained from influence functions of regular efficient estimators. Policy sensitivity has a local counterfactual interpretation, where the ceteris paribus change to a counterfactual distribution is specified by the combination of a control parameter and a Riemannian metric on the model manifold.
