%description
Simulates the results of completed randomized controlled trials, as if
they had been conducted as adaptive Multi-Arm Bandit (MAB) trials instead.
Augmented inverse probability weighted estimation (AIPW), outlined by
Hadad et al. (2021) <doi:10.1073/pnas.2014602118>, is used to robustly
estimate the probability of success for each treatment arm under the
adaptive design. Provides customization options to simulate
perfect/imperfect information, stationary/non-stationary bandits, blocked
treatment assignments, along with control augmentation, and other hybrid
strategies for assigning treatment arms. The methods used in simulation
were inspired by Offer-Westort et al.  (2021) <doi:10.1111/ajps.12597>.
