Dear Detlew,

❝ ❝ One of my 4-period full replicate studies (143 subjects, Method A)

❝

❝ Looks not too bad for a log-normal ;-) .

More details… The reference formulation in this study was terrible; CV_wR twice of CV_wT, many subjects with low AUCs after R. Distributions of studentized model residuals heavy-tailed. Since CV_wT <30%, this was a HVDP and not a HVD. Adjusting the AUC would make things worse.
90% CIs (Method B, Satterthwaite’s df):
AUC_0–∞: 111.17 – 123.79%
AUC_0–∞·k: 113.89 – 132.70%
