  "Description": "Design and analysis of one- and two-stage clinical trials\nusing Bayes factors. Implements methods for binomial and\ncontinuous endpoints, including point-null and directional\nhypotheses, power calculations, and sample size calibration.\nSupports one-arm trials with a single treatment arm and two-arm\ntrials with treatment and control arms. Includes methods for\nequivalence, non-inferiority, and superiority designs.",
