工具变量（IV）方法发明于70多年前，但在流行病学中仍然不常见。在过去的十年左右，非参数版本的IV方法已经出现，连接IV方法的因果关系和测量误差模型在流行病学应用中的重要性。本文介绍了这些发展，说明了IV方法的应用程序，非参数调整不遵守随机试验。
Instrumental-variable (IV) methods were invented over 70 years ago, but remain uncommon in epidemiology. Over the past decade or so, non-parametric versions of IV methods have appeared that connect IV methods to causal and measurement-error models important in epidemiological applications. This paper provides an introduction to those developments, illustrated by an application of IV methods to non-parametric adjustment for non-compliance in randomized trials.
