From: A novel pathway-based distance score enhances assessment of disease heterogeneity in gene expression
The accuracy of the clustering results when genes are dependent. The median purity criterion of the clustering results by hierarchical clustering (HC) and K-means clustering (Kmeans) using the three distances. The top two rows of panels describe the median purity criteria versus ρ for each given δ=0.5, 0.8, 1.1 and 1.5. The bottom two rows of panels describe the median purity criteria versus δ for each given ρ = 0.3 , 0.5 , 0.7 and 0.9
