Supports asymptotic bias correction for large panels (Bai 2009) and a dynamic extension for predetermined regressors (Moon and Weidner 2017 ). Includes information-criterion-based factor number selection (Bai and Ng 2002 ). Also implements an unbalanced panel extension using the expectation-maximisation algorithm of Bai (2009) with exact inferential statistics from Su, Wang and Wang (2025) , including nuclear-norm regularisation initialisation, singular value thresholding for factor number selection, and analytical bias correction for both strictly and weakly exogenous regressors. All computations use base R only with no external dependencies. authors: - family-names: Chen given-names: Binzhi email: Binzhi.Chen9@gmail.com preferred-citation: type: manual title: 'xtife: Interactive Fixed Effects Estimator for Balanced Panel Data' authors: - family-names: Chen given-names: Binzhi email: Binzhi.Chen9@gmail.com year: '2026' notes: R package version 0.1.3 url: https://CRAN.R-project.org/package=xtife repository: https://rickchen0910.r-universe.dev repository-code: https://github.com/Rickchen0910/xtife commit: e94c0fd2ad47ba7f9b52c1018f7ebb99fda8f687 url: https://github.com/Rickchen0910/xtife date-released: '2026-04-30' contact: - family-names: Chen given-names: Binzhi email: Binzhi.Chen9@gmail.com
