%description
The trigger strategy is a general framework for a multistage statistical
design with multiple hypotheses, allowing an adaptive selection of interim
analyses. The selection of interim stages can be associated with some
prespecified endpoints which serve as the trigger. This selection allows
us to refine the critical boundaries in hypotheses testing procedures, and
potentially increase the statistical power. This package includes several
trial designs using the trigger strategy. See Gou, J. (2023), "Trigger
strategy in repeated tests on multiple hypotheses", Statistics in
Biopharmaceutical Research, 15(1), 133-140, and Gou, J. (2022), "Sample
size optimization and initial allocation of the significance levels in
group sequential trials with multiple endpoints", Biometrical Journal,
64(2), 301-311.
