Applications of this method and the Danish Method have been documented 
in Last and Kubik (1981), Borre et al (1981), Borre et al (1983), and 
Jorgensen and Kubik (1983). 
6. FINAL COMMENTS 
It will salisfy many readers, that this paper imbeds robust estimntion 
methods in the classical (truncated) least squares elimination theory. We 
should consider, however, that this is only one of many possible 
interpretations, and work should continue on various different lines, in 
particular trying to establish proper confidence limits for the estimator.
