Abstract
In this paper we obtain an asymptotic expansion for the distribution o f Hotelling's T-2-statistic T-2 under nonnormality when the sample siz e is large. In the derivation we find an explicit Edgeworth expansion of the multivariate t-statistic. Our method is to use the Edgeworth ex pansion and to expand the characteristic function of T-2.
