QC-correlation analysis of concentration, largest The diagonal of the 10 x 10 matrix shows the histogram of variants for the independent measurements fragment value and fragment length at 3 QC (QC1, and triangular part of the matrix displays the absolute of the Pearson correlation coefficients between the pair of parameters (A). The lower triangular part displays the absolute value of the Spearman correlation coefficients and the upper triangular part displays the Kendall correlation (B. matrix are indicated with larger font sizes, smaller fonts are used for weak correlations. The upper triangular part of the displays the scatter plots between the pair of parameters, together with a best-fit line (red). The parameter shown on the x-axis of the scatter plot is given below inside the diagonal, and that on the y axis is given leftward inside the diagonal. Correlation coefficient ranges (no linear correlation: 0-0.5; weak correlation: 0.5-0.8; strong correlation: 0.8-1)
