WebLarger (positive or negative) log2 fold changes will result in larger increases or decreases. The final enrichment score is where the running-sum statistic is the largest deviation from zero. Step 2: Estimation of significance: Fold change is a measure describing how much a quantity changes between an original and a subsequent measurement. It is defined as the ratio between the two quantities; for quantities A and B the fold change of B with respect to A is B/A. In other words, a change from 30 to 60 is defined as a fold-change … See more There is an alternative definition of fold change, although this has generally fallen out of use.
