Abstract
The weighted least squares method using 1/x(2) as a weighting factor i s described and compared with conventional ordinary and weighted least squares and robust regression. Applications of these different method s to the relevant data sets demonstrates that the performance of the p rocedure discussed in this paper exceeds that of ordinary least square s method and equals, and often exceeds, that of weighted or robust met hods.
