The goal of adaptDiag is to simplify the process of
designing adaptive trials for diagnostic test studies. With accumulating
data in a clinical trial of a new diagnostic test compared to a
gold-standard reference, decisions can be made at interim analyses to
either stop the trial for early success, stop the trial for expected
futility, or continue to the next sample size look. Designs can be
focused around test sensitivity, specificity, or both. The package is
heavily influenced by the seminal article by Broglio et al. (2014).
