Statistical validation of abundance estimation (Figure S5). For each value of fraction of training set p, the relative deviation

is ranked and shown compared to its random counterparts (meaning that the identity of proteins with estimated abundance is randomly paired with the ones with real abundance values). The real deviation values are always on the left side (smaller than) of the random counterparts outside the error range, which implies its statistical significance.
