crt2power: Designing Cluster-Randomized Trials with Two ContinuousCo-Primary Outcomes
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.
