Data distribution in peptide 1:1 sample. a. MA plot of ASAPRatio. b. Histogram and corresponding KDE plot for the binary logarithmic ASAPRatio. c. Empirical CDF for the binary logarithmic ASAPRatio and one normal distribution with k- σ range given by Chebyshev’s Inequality, k=1,2,3. d. Cumulative probability within 3 σ range of the binary logarithmic ASAPRatio, the red dotted lines stand for the boundaries of [ μ±3σ]
