Title: Designing Cluster-Randomized Trials with Two Continuous
        Co-Primary Outcomes
Version: 1.2.2
Authors@R: c(person("Melody", "Owen", email = "melody.owen@yale.edu", role = c("aut", "cre")))
Description: Provides methods for powering cluster-randomized trials with two continuous co-primary outcomes using five key design techniques. Includes functions for calculating required sample size and statistical power. For more details on methodology, see Owen et al. (2025) <doi:10.1002/sim.70015>, Yang et al. (2022) <doi:10.1111/biom.13692>, Pocock et al. (1987) <doi:10.2307/2531989>, Vickerstaff et al. (2019) <doi:10.1186/s12874-019-0754-4>, and Li et al. (2020) <doi:10.1111/biom.13212>.
