- The miRNA–RNA pairs with a p-value \(\ge\) 0.01 were removed by the Wilcox test. The number of features was further reduced after dimension reduction by PCA of \(\Delta\)PCCs. In both MIC filtering and the Wilcox test, each feature represents a miRNA–RNA pair, In PCA, the number of features indicates the dimension of a feature vector
