Fig. 1 Posterior Bayesian fitting of PD20 as a function of dose for the 15 study subjects. Abscissa scaling is constant for all plots. Ordinate scaling varies with the observed maximal response of individual subjects. The plots reveal dose-response data with low variability (eg, subject 2) and high variability (eg, subject 13).
