WebThe ROC curves, and Table 4, suggest that GSEA (both gene permutation and phenotype permutation versions) and ssGSEA performed poorly regardless of the value of γ. Additionally, GSVA performed moderately better than these methods. ORA, ROAST, PAGE, GAGE, and PLAGE achieved a relatively higher area under the curve. Web10. máj 2014 · Permutation analysis furnishes p0 and p for possibly dependent SNPs so that these two p -values can be used to obtain the effective number of independent SNPs, which is given by neff = log (1 – p )/log (1 – p0 ).
