We establish a principle component analysis in the context of two-step monotone incomplete data drawn from a multivariate normal population. Data consists of n observations of p+q variables and additional N-n observations of p variables, where all observations are mutually independent. We perform the principal component analysis using the maximum likelihood estimator with the monotone incomplete data, derive the asymptotic distribution of the latent root of covariance matrix, and compare them with the results of the typical canonical correlation.
