Abstract.In the paper the main results of estimation theory in mixed models are collected and shortly explained. The estimation methods of unknown parameters corresponding to the expectation of the observed vector random variable as well as its dispersion matrix are presented in a unified form. The possibility of transforming the variance-covariance components model to the simpler one is also indicated.
