    Under the multivariate linear model {Y, Xβ ,Σ⨂V}, equality of MINQUE and so called simple estimator (1/f) Yt MY T 1 , with M=I-X(X`X)+XT, f = rank(X :V) - rank(X) for Σ is considered. It is revealed that this equality holds if and only if the quadratic form Σ-1 Y MY admits Wishart-distribution under multivariate normality of Y. Keywords: multivariate linear model, MINQUE, BLUE, OLSE, Wishart - distribution
