We show the results of performing the statistical analyses (a, b, and c) in Tables 6, 7, and 8, respectively.
This process is illustrated in Figure 2.
Only those risk factors where there is sufficient data (i.e., data from seven or more CRs) and the results are s-significant are shown.
Some quantitative risk factors (e.g., size of change, “sloc”) are s-significant;
no non-quantitative risk factors (e.g., complexity) are s-significant.
