Figure 8

Effect of noise. Effect of noise on (a) missing value rates, (b) quantification accuracy, (c) differential expression results, and (d) classification error rates. The x-axis represents α in the noise model given by Eqs. (7)-(8), while β is set to be 120α. The parameter values in the middle of the range (α = 0.04, β = 4.8) were estimated by an LC-MS analysis of human serum samples [19].
