In this paper we obtain an asymptotic expansion for the distribution of Hotelling's T 2 -statistic T 2 under nonnormality when the sample size is large. In the derivation we find an explicit Edgeworth expansion of the multivariate t-statistic. Our method is to use the Edgeworth expansion and to expa
