Convert mtd to rho_1 and vice-versa
Converting mtd to rho_1 given rho_0 for EWOC design using extended parametrization and vice-versa.
mtd_rho_d1extended(mtd = NULL, rho_1 = NULL, rho_0, theta, min_dose, max_dose)
mtd: a numerical value defining the mtd value to be converted into rho_1 value.rho_1: a numerical value defining the probability of DLT at the max_dose.rho_0: a numerical value defining the probability of DLT at the min_dose.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.mtd a numerical value for the maximum tolerable dose.
rho_1 a numerical value for the probability of DLT at the max_dose.
