Slope-based fault-proneness thresholds for software engineering measures
Sandro Morasca, Luigi Lavazza · 2016
Background. Practical use of a measure X for an internal attribute (e.g., size, structural complexity, cohesion, coupling) of a software module often requires setting a threshold on X, to make decisions as to which software modules may be estimated to be potentially faulty. To keep quality under control, practitioners may want to set a threshold on X to identify "early symptoms" of possible faultiness of a module, which should be closely monitored and possibly modified.
