We consider problems in finite-sample inference with two-step, monotone incomplete data drawn from N"d(@m,@S), a multivariate normal population with mean @m and covariance matrix @S. We derive a stochastic representation for the exact distribution of @m@^, the maximum likelihood estimator of @m. We obtain ellipsoidal confidence regions for @m through T^2, a generalization of Hotelling's statistic. We derive the asymptotic distribution of, and probability inequalities for, T^2 under various assumptions on the sizes of the complete and incomplete samples. Further, we establish an upper bound for the supremum distance between the probability density functions of @m@^ and @m@?, a normal approximation to @m@^.
