Biweight mid-correlation & bicor

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. See more Here we find the biweight midcorrelation of two vectors $${\displaystyle x}$$ and $${\displaystyle y}$$, with $${\displaystyle i=1,2,\ldots ,m}$$ items, representing each item in the vector as See more Biweight midcorrelation has been shown to be more robust in evaluating similarity in gene expression networks, and is often used for weighted correlation network analysis.
