| Abstract: | The paper concludes our investigations in looking for the locally best linear-quadratic estimators of mean value parameters and of the covariance matrix elements in a special structure of the linear model (2 variables case) where the dispersions of the observed quantities depend on the mean value parameters. Unfortunately there exists no linear-quadratic improvement of the linear estimator of mean value parameters in this model. |
| Keywords: | linear model with dispersions depending on the mean value parameters locally best linear-quadratic unbiased estimator (LBLQUE) of mean value parameters |
