adaptive_analysis_norm_global
                        Analyze data according to a globally efficient
                        adaptive design.
adaptive_analysis_norm_local
                        Analyze data according to a locally efficient
                        adaptive design.
adpss-package           adpss: A package for design and analysis of a
                        locally or globally efficient adaptive design
                        involving adaptive sample size determination.
exp_sample_size_norm_global
                        Calculate expected sample size for a globally
                        efficient adaptive design when working design
                        is followed until the final interim analysis
                        time and the final analysis time is fixed.
sample_size_norm_global
                        Calculate sample size or power for a globally
                        efficient adaptive design.
sample_size_norm_local
                        Calculate sample size or power for a locally
                        efficient adaptive design.
work_test_norm_global   Construct a working test and implement an
                        interim or the final analysis for a globally
                        efficient adaptive design.
