WebExample 1: Calculate Tukey’s biweight estimator for the data in range A4:A23 of Figure 1. The figure shows the calculation of the biweight estimator in Excel using 20 iterations (iterations 4 through 17 are not displayed), resulting in a value of 48.11807 (cell AU3). Actually, this level of precision was reached after only 13 iterations. http://users.stat.umn.edu/~sandy/courses/8053/handouts/robust.pdf

"WebTools. In statistics, biweight midcorrelation (also called bicor) is a measure of similarity between samples. It is median -based, rather than mean -based, thus is less sensitive to outliers, and can be a robust alternative to other similarity metrics, such as Pearson correlation or mutual information.
