Statistical Approach to Establishing Bioequivalence
... and there is a precedent for the use of such a procedure in the study of pharmacokinetics (Machado et al., 1999). Thus, asymptotic normal theory using restricted maximum likelihood (REML) will be used based on the modeling approach outlined by Jones and Kenward (2003). All the appropriate estimates ...
