Table 2 Formulas for selected distance matrix calculations
From: A variance component method for integrated pathway analysis of gene expression data
Method | Formula |
|---|---|
Bhjattacharyya distance | sqrt(sumi (sqrt(xi)–sqrt(yi))2) |
Correlation | xy/sqrt(xx * yy) for centered x,y |
Divergence distance | sumi (xi-yi)^2/(xi + yi)2 |
Euclidean distance | sqrt(sumi (xi-yi)2)) |
Extended Jaccard distance | xy/(xx + yy-xy) |
