%description
Implements the adaptive designs for integrated phase I/II trials of drug
combinations via continual reassessment method (CRM) to evaluate toxicity
and efficacy simultaneously for each enrolled patient cohort based on
Bayesian inference. It supports patients assignment guidance in a single
trial using current enrolled data, as well as conducting extensive
simulation studies to evaluate operating characteristics before the trial
starts. It includes various link functions such as empiric, one-parameter
logistic, two-parameter logistic, and hyperbolic tangent, as well as
considering multiple prior distributions of the parameters like normal
distribution, gamma distribution and exponential distribution to
accommodate diverse clinical scenarios. Method using Bayesian framework
with empiric link function is described in: Wages and Conaway (2014)
<doi:10.1002/sim.6097>.
