A Semiparametric Instrumented Difference-in-Differences Approach to Policy Learning

1 code implementation14 Oct 2023 Pan Zhao, Yifan Cui

In this article, we propose a general instrumented DiD approach for learning the optimal treatment policy.

Proximal Causal Learning of Conditional Average Treatment Effects

no code implementations26 Jan 2023 Erik Sverdrup, Yifan Cui

Efficiently and flexibly estimating treatment effect heterogeneity is an important task in a wide variety of settings ranging from medicine to marketing, and there are a considerable number of promising conditional average treatment effect estimators currently available.

Individualized Decision-Making Under Partial Identification: Three Perspectives, Two Optimality Results, and One Paradox

no code implementations21 Oct 2021 Yifan Cui

Secondly, building on this unified framework, we provide a novel minimax solution (i. e., a rule that minimizes the maximum regret for so-called opportunists) for individualized decision-making/policy assignment.

On a necessary and sufficient identification condition of optimal treatment regimes with an instrumental variable

no code implementations7 Oct 2020 Yifan Cui, Eric Tchetgen Tchetgen

Unmeasured confounding is a threat to causal inference and individualized decision making.

Estimating heterogeneous treatment effects with right-censored data via causal survival forests

2 code implementations27 Jan 2020 Yifan Cui, Michael R. Kosorok, Erik Sverdrup, Stefan Wager, Ruoqing Zhu

Forest-based methods have recently gained in popularity for non-parametric treatment effect estimation.

A semiparametric instrumental variable approach to optimal treatment regimes under endogeneity

no code implementations21 Nov 2019 Yifan Cui, Eric Tchetgen Tchetgen

There is a fast-growing literature on estimating optimal treatment regimes based on randomized trials or observational studies under a key identifying condition of no unmeasured confounding.

Robust classification

Selective machine learning of doubly robust functionals

no code implementations5 Nov 2019 Yifan Cui, Eric Tchetgen Tchetgen

While model selection is a well-studied topic in parametric and nonparametric regression or density estimation, selection of possibly high-dimensional nuisance parameters in semiparametric problems is far less developed.
