Suppose that we have \((n-a)\) independent observations from \(N_{f}(0,2)\) and that, in addition, we have \(a\) independent observations available on the last \((p-c)\) coordinates. Assuming that both observations are independent, we consider the problem of estimating \(\sum\) under the Stein's los
