Closed forms are obtained for maximum likelihood estimates (MLE) of multivariate normal with missing data using auxiliary information. The likelihood function is obtained as product of several independent normal and conditional normal likelihood functions. The parameters are transformed into a new set of parameters of which the MLEs are easy to derive. Since the MLEs are invariant, the MLEs of the original parameters are derived using the inverse transformation.
