Hi John,

❝ Missing observations ⇒ Does that mean we would encounter problems if not all subjects have data for each treatment? i.e, what if we miss some AUCinf values when kel cannot be determined?

There might be a small bias. However, sequences would have to be extremely imbalanced/incomplete to start hurting. Look at FDA’s replicate example data sets.
n_AUC∞ ≠ n_AUCt is rather a rule than an exception.
