M-estimates are consistent estimates of multivariate location and shape, so the biweight correlation is estimating …
Webbiweight correlation can be used as a resistant similarity measure or a diagnostic procedure for °agging data. We then demonstrate, in section 2.4, that our method is more e–cient than Spearman correlation (another resistant correlation method.) In section 2.5 we show that the biweight correlation has empirically
