Fig. 4From: Similarity assessment of quality attributes of biological medicines: the calculation of operating characteristics to compare different statistical approachesSample size dependency of average operating characteristics (Tolerance Interval): The average operating characteristics are shown for different test and reference product sample sizes (nref = 4,6,8,...,30, ntest = 4,6,8,...30) for the test Tolerance Interval. Arrows indicate the effect of increasing test product and reference product sample size (annotated as ntest and nref, respectively). In contrast to Fig. 3, the x-axis for the false acceptance rates is extended in order to visualize all data pointsBack to article page
