Conditional unconfoundedness
Web∙Unconfoundedness generically maintains that we have enough controls – usually pre-treatment covariates and outcomes – so that, conditional on those controls, treatment … In statistics, ignorability is a feature of an experiment design whereby the method of data collection (and the nature of missing data) does not depend on the missing data. A missing data mechanism such as a treatment assignment or survey sampling strategy is "ignorable" if the missing data matrix, which indicates which variables are observed or missing, is independent of the missing data conditional on the observed data.

WebThe underlying identifying assumption is unconfoundedness (selection on observables or conditional independence). Intuition: If the decision to take the treatment is purely random for individuals with similar values of the pre-treatment variables, then we could use the average outcome of some similar individuals who were not exposed to the ... Web图7. positivity和unconfoundedness 可以发现，随着X个数的增多，positivity假设成立的可能也越小。但刚好我们控制的X个数越多，满足unconfoundedness的可能性也越高，这说明positivity和unconfoundedness很难两全，我们在实验中往往需要在二者间做一个权衡。

This paper proposes an alternative test procedure for testing the conditional unconfoundedness assumption which is an important identification condition commonly imposed in the literature of program analysis and policy evaluation. We transform the conditional unconfoundedness test to a nonparametric conditional … WebNov 1, 2010 · 1. Introduction. This note describes two new approaches for testing a conditional form of exogeneity ensuring unconfoundedness. Suppose data are generated by the structural equation (1) Y = r (D, Z, U), where Y is a scalar response of interest, r is the unknown structural function, and D, Z, and U are drivers of Y. U is …

WebDec 13, 2024 · We consider estimation and inference on average treatment effects under unconfoundedness conditional on the realizations of the treatment variable and covariates. Given nonparametric smoothness and/or shape restrictions on the conditional mean of the outcome variable, we derive estimators and confidence intervals (CIs) that …
