Dose-response curves for the piecewise quadratic-logistic for different nominal values of θ: θ = (834, 0.035, 1.45, 38)T (dotted), θ = (164, 0.04, 1.5, 44)T (light gray), θ = (294, 0.037, 1.48, 44)T (dark gray). The black solid line corresponds to the fitted response from the exp+logistic model when θ = (0.15, 85, 3.4, 45)T.
