The solid line is the true log-likelihood ratio function, the dotted line is Approximation (6), and the dashed line is Approximation (7). The values of η0 are 1.099 in (a) and −0.571 in (b). Since the closed-form map from mean-value parameters ξ to canonical parameters η is known, the range of η values corresponding to the range of sampled statistics is shown as a short segment with its endpoints marked in each plot.
