Citace:
Abstrakt: The definition of Instrumental Weighted Variables (IWV) (which is a robust version
of the classical Instrumental Variables) and conditions for the weak consistency as given
in V\'{\i}\v{s}ek (2009) are recalled. The reasons why the classical Instrumental
Variables were introduced as well as the idea of
weighting the order statistics of squared residuals (rather than directly the squared residual - firstly employed by the Least Weighted
Squares, see V\'{\i}\v{s}ek (2000)) are also recalled. Then $\sqrt{n}$-consistency
of all solutions of the corresponding normal equations is proved.
