Package: ssMRCT Type: Package Title: Regional Consistency Evaluation and Sample Size Calculation for MRCTs Version: 0.2.0 Authors@R: c( person("Kunhai", "Qing", role = c("aut", "cre"), email = "kunhaiq@stu.ecnu.edu.cn"), person("Xinru", "Ren", role = "aut"), person("Jin", "Xu", role = "aut")) Description: Calculate conditional regional consistency probabilities and sample sizes for multi-regional clinical trials under fixed-effects and random-effects models. Supports two independent trials, regional fraction selection under symmetric designs, and doubly robust regional treatment-effect estimation. Methods include Qing et al. (2025) and Ren and Xu (2026) .
