In UnifiedDoseFinding: Dose-Finding Methods for Non-Binary Outcomes

Generate operating characteristics for finding the maximum tolerated dose (MTD) of continuous endpoint using design by Ivanova et al (2009)

Description

Obtain the operating characteristics of the dose-finding design of continuous endpoint by Ivanova et al (2009)

Usage

get_oc_Ivanova_continuous(target, eps = 1, ptox, ncohort,
                          cohortsize, n.earlystop = 100,
                          ntrial, startdose = 1, seed = 100)

Arguments

target	the continuous target score
eps	the decision criterion. The default value is eps = 1
ptox	the true mean value of the continuous measure
ncohort	the number of cohorts
cohortsize	the cohort size
n.earlystop	the early stopping parameter. The default value is n.earlystop = 100
ntrial	the number of simulated trials
startdose	the starting dose level. The default value is startdose = 1
seed	the seed. The default value is seed = 100

Value

get_oc_Ivanova_continuous() returns the operating characteristics of Ivanova design as a list object, including: (1) selection percentage at each dose level (2) patients treated at each dose level
