ToxCrit: Calculates Safety Stopping Boundaries for a Single-Arm Trial
using Bayes
Computation of stopping boundaries for a single-arm trial using a
Bayesian criterion; i.e., for each m<=n (n= total patient number of the
trial) the smallest number of observed toxicities is calculated
leading to the termination of the trial/accrual according to the specified
criteria. The probabilities of stopping the trial/accrual at and up until
(resp.) the m-th patient (m<=n) is also calculated. This design is more
conservative than the frequentist approach (using Clopper Pearson CIs)
which might be preferred as it concerns safety.See also Aamot et.al.(2010)

of stopping prematurely" <doi:10.5414/cpp48476>.
