Abstrakt: | Weak $\sqrt{n}$-consistency of the {\it Least Weighted Squares } estimator of the coefficients of regression model is proved generally under the heteroscedasticity of error terms. The assumptions required for the weak $\sqrt{n}$-consistency are briefly discussed. The roots of the heteroscedasticity are also critically considered. |
