RQ2: Is static code analysis suitable to compute TestI?

DTestI is a better predictor of changes in controllers than TestI

Recall values for TestI and DTestI, considering CF (controller-filter) and NF (no filter) configurations.

Precision values for TestI and DTestI, considering CF (controller-filter) and NF (no filter) configurations.

Wilcoxon Signed-Rank test applied to precision and recall measures of TestI and DTestI
