Likelihood ratio test for independence with partial multivariate normal data. (English) Zbl 0644.62062

Summary: This article derives the likelihood ratio statistic to test the independence between \((X_ 1,...,X_ r)\) and \((X_{r+1},...,X_ k)\) under the assumption that \((X_ 1,...,X_ k)\) has a multivariate normal distribution and that a sample of size n is available, where for N observation vectors all components are available, while for \(M=(n-N)\) observation vectors, the data on the last q components, \((X_{k- q+1},...,X_ k)\) are missing (k-q\(\geq r)\).
