| Abstract: | :In this paper strating from the more General functional model, a universal formula of maximum likelihood estimation of variance-covariance components, which can be applied to all least squares adjustment models, has been derived. It is shown that both formulas derived by K. Kubik and C. R. Koch are as special cases of this estimator. |
