Abstract: 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.
