bfbin2arm: Bayes Factor Design for Two-Arm Binomial Trials

Design and analysis of one- and two-stage two-arm binomial clinical phase II trials using Bayes factors. Implements Bayes factors for point-null and directional hypotheses, predictive densities under different hypotheses, and power and sample size calibration.
