Package: MRStdCRT Type: Package Title: Model-Robust Standardization in Cluster-Randomized Trials Version: 0.1.3 Authors@R: c( person(given = "Jiaqi", family = "Tong", role = "aut"), person(given = "Changjun", family = "Li", role = c("aut","cre"), email = "changjun.li@yale.edu"), person(given = "Xi", family = "Fang", role = "aut"), person(given = "Chao", family = "Cheng", role = "aut"), person(given = "Kenneth M.", family = "Lee", role = "aut"), person(given = "Bingkai", family = "Wang", role = "aut"), person(given = "Fan", family = "Li", role = "aut")) Description: Implements model-robust standardization for cluster-randomized trials (CRTs). Provides functions that standardize user-specified regression models to estimate marginal treatment effects. The targets include the cluster-average and individual-average treatment effects, with utilities for variance estimation and example simulation datasets. Methods are described in Li, Tong, Fang, Cheng, Kahan, and Wang (2025) . Inverse-cluster-size weighted outcome models are available for generalized estimating equations and linear or generalized linear mixed models. The outcome models can use common fitting weights for both estimands or inverse-cluster-size weights for the cluster-average effect and no weights for the individual-average effect. Inference retains the original standardization framework and paired cluster jackknife. Related cluster-size saturated models are described in the arXiv preprint by Lee, Harhay, and Li (2026) .
