Modified Toxicity Probability Interval Design
Web27 mei 2024 · In 2010, Ji et al 38 proposed a modified toxicity probability interval (mTPI) with improvements, including overdose protection, calibration free, and correspondence to Bayes rule. In mTPI design, an equivalence interval (pT − ε1, pT + ε2), ε1, ε2 ≥ 0 was set.
