An idea of implicit estimating the scale of disturbances, implicitly appearing in the least median of squares, the least trimmed squares, and the least weighted squares, found its explicit expression in the S-estimators. A similar idea of weighting order statistics of squared residuals, also implicitly employed in the least median of squares and the least trimmed squares, was in full generality used by the least weighted squares. A combination of these two idea yielded a new, flexible type of methods - the S-weighted estimators. Their properties, especially consistency is studied. |
