rho: a numerical vector indicating the true value of the parameters rho_0 and rho_1.
theta: a numerical value defining the proportion of expected patients to experience a medically unacceptable, dose-limiting toxicity (DLT) if administered the MTD.
min_dose: a numerical value defining the lower bound of the support of the MTD.
max_dose: a numerical value defining the upper bound of the support of the MTD.
dose_set: a numerical vector of doses that probability of DLT will be calculated.
