The estimator is recommended by Słoczyński (2024) <doi:10.48550/arXiv.2011.06695> as an alternative to two-stage least squares when estimating the interacted specification of Angrist and Imbens (1995) <doi:10.1080/01621459.1995.10476535>.https://github.com/r-universe/qihui-lei/actions/runs/25785107896Tue, 14 Oct 2025 18:20:15 GMTfejiv0.1.1successhttps://qihui-lei.r-universe.devhttps://github.com/cran/fejiv
