%description
Implement group response-adaptive randomization procedures, which also
integrates standard non-group response-adaptive randomization methods as
specialized instances. It is also uniquely capable of managing complex
scenarios, including those with delayed and missing responses, thereby
expanding its utility in real-world applications. This package offers 16
functions for simulating a variety of response adaptive randomization
procedures. These functions are essential for guiding the selection of
statistical methods in clinical trials, providing a flexible and effective
approach to trial design. Some of the detailed methodologies and
algorithms used in this package, please refer to the following references:
