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,
