Figure 1From: A comparative study on gene-set analysis methods for assessing differential expression associated with the survival phenotypeThe estimated size and power of the five tests, GSEA1, GSEA2, GT, WT and GBST, over the proportions of significant genes in each gene-set, using four different correlation structures, two different scenarios for generating the Cox regression coefficient vector, and censoring level c p = 0.0. The solid and the dashed lines correspond to Case (A), that genes are positively associated with the survival times, and to the Case (B), that genes are randomly associated with the survival time, respectively. The circle, square, diamond, triangle and inverted triangle symbols correspond to GSEA1, GSEA2, GT, WT and GBST, respectively.Back to article page
