WebJan 1, 2024 · The performance of the proposed method is primarily compared with Biweight mid correlation (BICOR) ... Spearman rank correlation (SRC) [30], and BICOR [14] in terms of the PPVs at various similarity values and also at various number of top gene pairs. The GAAWGEFA increases the expression similarity for the functionally similar gene pairs. 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.
