I found this usefull website http://cbio.mskcc.org/tcga-generanker/index.jsp based on mutliple cancer gene list. I searched, but I cannot find any information on how this tcga-generanker is made ? and which statistics it used to compute the score ? And also it says Gene Ranker: TCGA GBM 6000. Is it only for GBM (Glioblastoma Multiforme) .
