When we pooled data from different studies in patients, healthy volunteers and involving different formulations, it was anticipated that the residual error would not be constant across all individuals. We have published the application of this methodology in BJCP: Kerbusch T, Whlby U, Milligan PA, Karlsson MO. Br J Clin Pharmacol, 2003; 56(6): 639-652 Kerbusch T, Milligan PA, Karlsson MO.
