title: The impact of outlying subjects on decision of bioequivalence.
abstract: As a consequence of a hearing on bioequivalence conducted by the Food and Drug Administration in 1986, the identification and the treatment of a potential outlier in bioequivalence trials has become an important issue in the assessment of bioequivalence because the exclusion of a statistically identified outlier may lead to a totally different conclusion on bioequivalence. In this paper, we examine the impact of a statistically identified outlying subject on the decision of bioequivalence through a simulation study under the structure of a standard two-way crossover design based on interval hypotheses for bioequivalence. The Hotelling T2 test suggested by Liu and Weng (1) is used for detection of an outlying subject.
