It is designed for causal panel analysis with binary treatments under the parallel trends assumption. The package supports scenarios where treatments can switch on and off and allows for limited carryover effects. It includes several imputation estimators, such as Gsynth (Xu 2017), linear factor models, and the matrix completion method. Detailed methodology is described in Liu, Wang, and Xu (2024) and Chiu et al. (2025) . Optionally integrates with the "HonestDiDFEct" package for sensitivity analyses compatible with imputation estimators. "HonestDiDFEct" is not on CRAN but can be obtained from . authors: - family-names: Xu given-names: Yiqing email: yiqingxu@stanford.edu - family-names: Liu given-names: Licheng email: lichengl@stanford.edu - family-names: Liu given-names: Ziyi email: zyliu2023@berkeley.edu - family-names: Wang given-names: Ye email: yezhehuzhi@gmail.com - family-names: Qin given-names: Tianzhu email: tianzhu@stanford.edu - family-names: Hu given-names: Shiyun email: hushiyun@pku.edu.cn - family-names: Lipkovitz given-names: Rivka email: rivkal@mit.edu repository: https://xuyiqing.r-universe.dev repository-code: https://github.com/xuyiqing/fect commit: eccc9731ad74d049b22a3e769393c6a6c47b33bd url: https://yiqingxu.org/packages/fect/ date-released: '2026-05-29' contact: - family-names: Xu given-names: Yiqing email: yiqingxu@stanford.edu
