The paper presents basic properties of the VRy-estimation. Some forms of the correcting function and gain functions were proposed. These functions influence substantially the course and properties of the proposed estimation method.
A method of estimation which allows to obtain robust, efficient, invariant and unbiased estimator of the variance coefficient [formula] is derived in the work. The coefficient [formula] occurs in the model of covariance matrix of observation results [formula]. It is assumed that the class of square estimators of the following general form [formula]. The method presended in the paper is the development...
