%description
Implements group response-adaptive randomization procedures, which include
standard (non-group) response-adaptive randomization methods as special
cases. The package also handles delayed and missing responses, which
broadens its use in real-world trials. It offers functions for simulating
a variety of response-adaptive randomization procedures, to help guide the
choice of design for a clinical trial, including the doubly adaptive
biased coin design and the multi-arm efficient randomized adaptive design
(ERADE), k-arm optimal target allocations, group sequential monitoring,
and a function that computes allocation probabilities for an ongoing
trial. For details of the methods and algorithms, see the following
