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 See more Biweight midcorrelation has been implemented in the R statistical programming language as the function bicor as part of the WGCNA package Also implemented in the Raku programming language as the function bi_cor_coef as part … See more WebJun 25, 2007 · Additionally, our method gives a systematic gene flagging procedure which is useful when dealing with large amounts of noisy data. Conclusion: When dealing with microarray data, which are known to be quite noisy, robust methods should be used. Specifically, robust distances, including the biweight correlation, should be used in … WebDec 3, 2024 · Traditional correlation measures provided in NetCoMi are the Pearson correlation, Spearman’s rank correlation and the biweight midcorrelation (bicor). Bicor as part of the R package WGCNA [ 52 ] is more robust to outliers than Pearson’s correlation because it is based on the median instead of the mean of observations. polywood picnic table with detached benches
