Package: sreg Type: Package Title: Stratified Randomized Experiments Version: 2.0.2 Authors@R: c( person("Juri", "Trifonov", email = "jutrifonov@u.northwestern.edu", role = c("aut", "cre", "cph")), person("Yuehao", "Bai", email = "yuehao.bai@usc.edu", role = "aut"), person("Azeem", "Shaikh", email = "amshaikh@uchicago.edu", role = "aut"), person("Max", "Tabord-Meehan", email = "m.tabordmeehan@utoronto.ca", role = "aut")) Description: Estimate average treatment effects (ATEs) in stratified randomized experiments. `sreg` supports a wide range of stratification designs, including matched pairs, n-tuple designs, and larger strata with many units — possibly of unequal size across strata. 'sreg' is designed to accommodate scenarios with multiple treatments and cluster-level treatment assignments, and accommodates optimal linear covariate adjustment based on baseline observable characteristics. 'sreg' computes estimators and standard errors based on Bugni, Canay, Shaikh (2018) ; Bugni, Canay, Shaikh, Tabord-Meehan (2024+) ; Jiang, Linton, Tang, Zhang (2023+) ; Bai, Jiang, Romano, Shaikh, and Zhang (2024) ; Bai (2022) ; Bai, Romano, and Shaikh (2022) ; Liu (2024+) ; and Cytrynbaum (2024) .
