AssignEffTox            Determines the optimal dose to assign the next
                        patient cohort.
EFFTOX                  Obtains estimated posterior probabilities of
                        the four outcomes of (YE,YT) for each dose.
PieceMCMC               Returns posterior distribution for key mixture
                        model parameters
RandomEffTox            Randomizes Eff-Tox dose proportional to
                        posterior desireability scores.
Reoptimize              Gives the Optimal Dose for enrolling next
                        patient cohort.
Reoptimize1             Gives the Optimal Dose for enrolling next
                        patient cohort. Used in the SimPhase123
                        function.
ReturnMeanControl       Gives true mean survival times for the control
                        therapy.
ReturnMeansAgent        Gives true mean survival times for doses
                        considered of the experimental agent.
ReturnOCS               Gives operating characteristics of phase 123
                        and conventional design.
RunAdaptiveEffToxTrial
                        Simulates repitions of an Adaptive Eff-Tox
                        Trial.
SimPhase123             Simulates replications of the phase123 and
                        phase 12-3 trials.
SimPhase3               Performs one replication of phase 3 for the
                        phase 123 design, given phase 12 data.
