  21. Statistical assessment of predicted links between compounds and targets • We merged all the predictions from the 3 methods. • Significance of links using groups of similar compounds and the targets KEGG pathways . • LogOdds. Odds of an observation given its probability. • p-value using Fisher´s exact test for 2x2 contingency table comparing two groups of annotations. Thursday, September 25, 14
