The Method of Changing Quadratic Estimation into Linear Estimation
This paper presents a new model of variance and covariance components estimation by applied projective transformation and representation of matrices by vectors. The method changes the quadratic estimation of varisnce and covarisnce components into the linear model.Some statistical characters of the estimate have been proved.
