Abstract

The paper studies S-weighted estimator - a combination of S-estimator and the least weighted squares. The estimator allows to adjust the properties, namely the level of robustness of estimator in question to the processed data better than the S-estimator or the least weighted squares can do. The paper offers the proof of its \(\sqrt{n}\)-consistency.

That is why that although LTS was defined in eighties, the general proofs of its properties appeared as late as in 2006, see [16].

It is clear from Fig. 1 that any estimator with high breakdown point generally suffer by “switch effect” but the Engine Knock Data indicate that it can happen for much lower breakdown point.

We experimented with various numbers of repetitions - smaller than 100 exhibited some instability in MSE, in the sense that repeated simulations (yielding one particular table - see below) gave (rather) different information about the dispersion of the estimates for individual datasets, - the number of repetitions larger than 100 gave a lower information about the preciseness of estimation by \(\hat{\beta }^{(method)}_j\) (see (14)) just resulting in exact “true values of coefficients”, see (13).
