WebThis function implements biweight midcorrelation calculation (see references). If y is not supplied, midcorrelation of columns of x will be calculated; otherwise, the midcorrelation … WebSpecifically, we calculated pair-wise biweight mid-correlations (bicor, a robust correlation metric) between each protein pair and transformed that matrix into a signed adjacency matrix (Langfelder and Horvath 2012). ... Hierarchical protein correlation clustering analysis by this approach was conducted using 1-TOM, and initial module ...
WebThe module-trait heatmap usually represents the correlations of the module eigengenes with traits. When that correlation is high, it means the eigengene increases with increasing trait. In a signed network (where all genes in a module are positively correlated with the eigengene) it will mean that (again if the eigengene-trait correlation is ...

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.
